ef382ef7b6 Fixed dependencies for scrt0.o.
Build a static gcrt0.o (sgcrt0.o) too.  Currently only the dynamic gcrt0.o
is used, although -pg forces -static.
Sorted the .o targets.

a026489209 -fomit-frame-pointer is becomming an increasingly popular optimization,
so before somebody screws up royally, make sure this always works by
adding a -fno-omit-frame-pointer here.

361585330b put the _getenv and _strncmp under #ifdef DEBUG, which is the only time
they are used.  Saves a few bytes here and there, nothing major.

aa55f7313a Create a scrt0.o file that specifically excludes the shared-lib support.
This will be used for -static programs.

f12729acb8 Fixup the "ld.so failed" message for the case when ld.so finds undefined
symbols.

An easy example to see this is to develop an X program which links
against Xt, but doesn't add -lX11 to the link line.  It will link fine,
but cause run-time errors by ld.so because of missing symbols used by Xt
defined in X11.  This patch makes the errors more readable.

6579f34131 Change install' to ${INSTALL}' so that default install flags can be
specified in the top level Makefiles.

Previously I missed dozens of Makefiles that skip the install after
using `cmp -s' to decide that the install isn't necessary.

ceb5359a6a Numerous Makefile fixes:
1) Do dependencies.
2) Install all appropriate links to manual pages.
3) Install header file in `beforeinstall' like all the rest.
4) Install header file only if changed.
5) Install object files only if changed.

6da3ef3223 Change ld.so to correctly load dependant libraries for dlopen and unload them
on dlclose.  Also correctly call constructors and destructors for libraries
linked with /usr/lib/c++rt0.o.
Change interpretation of dlopen manpage to call _init() rather than init()
for dlopened objects.
Change c++rt0.o to avoid using atexit to call destructors, allowing dlclose to
call destructors when an object is unloaded.
Change interface between crt0 and ld.so to allow crt0 to call a function on
exit to call destructors for shared libraries explicitly.

These changes are backwards compatible.  Old binaries will work with the new
ld.so and new binaries will work with the old ld.so.  A version number has
been introduced in the crt0-ld.so interface to allow for future changes.

0de4aa5096 Add (#ifdef'ed by STARTUP_LOCALE) following line to crt0.c
(void) setlocale(LC_ALL, "");

It will be easiest way now to make national chars available
for all ctype-oriented programs at once by simple:

setenv LANG Your_National_Charset

Default case (without "LANG" environment
variable) will be fully ANSI compatible (got "C" locale).

If "LANG" variable present, extention becomes active.

Effect of this extention is great: in one time all ctype
oriented programs can accept/print national characters
without any touching source/binary code, it is big win, IMHO.

This method is fully compatible with ISO8859-* and russian koi8-r
too (in general -- with all 8-bit character sets). I think
it is very useful.
I got this idea from Xenix locale implementation.

This extention is even never compiled in, unless you set
	setenv STARTUP_LOCALE
before rebuilding crt0.c or corresponding variable in /etc/make.conf

e1f08fe22b Remove dead code. gmon stuff is now done better in libc/gmon an
<machine/profile.h>.  The old version was writing an incomplete
header without the profrate field that is necessary to handle the
current faster profiling clock.  The counters that are where the
the profrate should be are usually 0 and gprof converts a profrate
of 0 to hz so the old version gave times too large by a factor of
profhz/hz = 10.24.

0dbc086d98 From Jordan via. Paul K.
This fixes the problems Warner's having with ctors not being called
again with the latest round of ld changes and updates the file-names to what
Paul is using now.

The name change will not affect anything as we are not (yet) using it.

c06d5da754 Yanked out the 8 'addb %al,%al' (0xc000)'s out of the start of the
program. The idea was that these are 'alignment' crap, but the image
is 16byte-aligned without these. Location 0 still doesn't have a 0,
but who cares, binaries wil be built with page zero unmapped in the
near future.
