to generate the special .type and .size directives which are used to set
the corresponding fields of the linker symbol table entries in the ELF
object file. As such they are not i386-specific and thus belong in our
MI header. Otherwise on the Alpha we don't properly give the type and
size of dynamic symbols. Bintuil versions past 2.9.1 warn of this and
w/o this change, `ld' generates a lot of warnings during a `make world'.
I did not catch this on the EGCS 1.1.x --> GCC 2.95 upgrade.
So propogate this change to our custom hacks.

"The problem is that egcs/gcc-2.95's reorganisation of the prologue and
epilogue code to use rtl instead of output_asm_insn() completely broke our
hooks. rtl is emitted in a different order, only after optimisation, while
output_asm_insn() is emitted immediately. rtl is presumably used so that
the prologue and epilogue can be optimised.
I couldn't find any good examples to copy. gcc's own
FUNCTION_BLOCK_PROFILER still uses output_asm_insn() and seems to be
completely broken. One of the XXX comments points to this.
IIRC, the hacks here basically arrange to emit magic label names; then when
the magic names are output, they are transformed into prologue and epilogue
code."

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.
Submitted by: marcel (in a different format and reworked by me)
of changing the search dirs. This also removes an used search dir,
removes unneeded redundancy, and a bugus dir we enherited on the i386
by baseing off of svr4.h.
We went from:
install: /usr/libexec/(null)
programs: /usr/libexec/<OBJFORMAT>/:/usr/libexec/:/usr/bin/:/usr/libexec/
libraries: /usr/libdata/gcc/:/usr/libexec/:/usr/ccs/lib/:/usr/lib/
to:
install: /usr/libexec/(null)
programs: /usr/libexec/<OBJFORMAT>/:/usr/libexec/
libraries: /usr/libexec/:/usr/lib/
* Don't conditional based on i386, but generalize to all FreeBSD arch's.
* Don't be a.out-centric, but generalize to handle other possible future
formats.

* Commonalities with i386, moved to a FreeBSD wide config file.
* Major additions to this file were adapted from Hidetoshi Shimokawa
<simokawa@FreeBSD.ORG>'s Alpha suppliment to the Egcs 1.1.2 port.
