idea after all.
Fix cross-builds and ia64 builds. gnu/lib/csu/Makefile is modified to
pre-include osreldate.h and gnu/usr.bin/cc/cc_tools/auto-host.h
will avoid including sys/param.h if __FreeBSD_version is already defined.
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.

now only produce ELF objects. It also makes us closer to stock GCC, and
simplifies the set of changes we still need from stock GCC on every import.

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.

the source tree -- it was too easy to get out of sync, so the other
instances now use this instance.

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'.
