non-PIC libgcc.a. Linking non-pic code into a shared library is not
a good thing. It happens to break amd64 at compile time, and the ppc
folks want it too. The problem is mainly with C++ code, unwind-dw2.c
in particular. Most of the other functions in libgcc.a are self
contained so most of the time it isn't a problem. The dwarf2 unwinder
is not safe though since it does make global variable references.

The problem is the GCC driver now turns STANDARD_EXEC_PREFIX into a relative
path -- "<basename argv[0]>/../../libexec" for our normal install location.
However, in the middle of `buildworld' we need
"<basename argv[0]>/../../../../libexec" due to the prefix we tell the GCC
driver. But either the GCC driver is buggy, or we are confusing it, as it
tries to exec "<basename argv[0]>/../../libexec/cpp0" as if it were installed
in the normal place (but isn't).
MD_EXEC_PREFIX is still absolute, so I'll use that for now. I would like to
later make it so MD_EXEC_PREFIX is set only for `buildworld', as
MD_EXEC_PREFIX is also in the search path for libraries. Don't ask me why!
Another way is to add ${OBJFORMAT_PATH} (as set in CROSSENV) to the PATH
in src/Makefile.inc's WMAKEENV.
about 'STANDARD_EXEC_PREFIX'. It is used now and is needed if one does not
set 'MD_EXEC_PREFIX'.
Do not define a 'MD_EXEC_PREFIX'. It is not needed, not used in the
cross case, and just ends up causing "/usr/libexec" being added to the
library search path.

* Undo the diking out of cross compiler logic from gcc.c rev 1.16.
* Add the `CROSS_STARTFILE_PREFIX' knob.
* Add our own definition of `STANDARD_INCLUDE_DIR'. This should have been
included in freebsd-native.h rev 1.5.
I am committing this here rather than in gcc/config/freebsd.h because the
profiled libgcc only exists with the native system compiler. It is not
created by a stock FSF build and we will never be able to get these bits
committed to the FSF CVS repo. Thus this is very much a FreeBSD "native"
issue.

Also remove misleading comment about 'STANDARD_EXEC_PREFIX'. It is needed
if one does not set 'MD_EXEC_PREFIX'.

Really irritating changes are the "forced" layering of malloc + friends
in order to use the GNU versions. Sorry, we have a *very* fine malloc,
and we will use it. Period. Even more irritating is that the GNU people
now want to replace ctype also!! So we partially dike it out here.
of stuff (and thus length of error output) we put on the invocation command
line. Also follow the new FSF/GNU style of giving the symbol a value so it
can be used in `if()' statements in addition to `#if' so seldomly compiled
in code (on some platforms) gets compiled always, to help reduce bit-rot.

LinuxThreads port. Dike it out as it was removed from freebsd.h on
19-July-2000 as this option depended on bits not part of the base system
and required people to install the LinuxThreads port in a manner
non-consistent with the workings of our Ports Collection.

If one wishes to anchor the compiler toolchain tree somewhere other than /,
all one needs to do is set "TOOLS_PREFIX" to a different rooting.

removes unneeded redundancy, and a bugus dir we enherited on the i386
