* be consistant on protecting "#define FOO"s with "#undef FOO".
* be consistant that macro params are upper case, and commas are followed
by a space in the macro definition
* protect macro param expansion by ()'s

* remove trailing spaces
FreeBSD wide config file.
This includes "WORD_SWITCH_TAKES_ARG" & "SWITCH_TAKES_ARG". Platforms
such as FreeBSD/MIPS will need to override these two defintions, but it
can #undef them and define them approapiately.
* In the absence of the env vars TMPDIR, TMP, TEMP (which override this
ordering), attempt to create temperary files in /tmp, P_tmpdir (/var/tmp),
/usr/tmp, and . until successful.
* Support for our dual ELF/a.out building ability
* Our custom ASM_* definitions
* Our custom debugger and profiling related definitions
* Our custom STARTFILE/ENDFILE specs
* The stock EGCS 1.1.2 freebsd-elf.h file depended on
egcs-1.1.2/gcc/config/linux.h, which included "svr4.h". We will
include "svr4.h" via our "tm.h" definition. So add the few bits
from "linux.h" we actually needed.
* Using our current crtbegin.o/crtend.o we cannot support the DWARF2
unwinding mechanisms. In the future we will switch to the
non-sjlj-exceptions type exception machanism. However the `make world'
bootstrap problems with the EGCS crtstuff.c must be overcome first.
* Our a.out gas doesn't "know" to use NOP's for aligns while in the text
section. Thus the a.out alignment generation needed tweaking from
what we did with GCC 2.7.2. [from BDE]
* The definition of SUPPORTS_ONE_ONLY prevents the compiler from trying
to use "linkonce" sections for a.out. The definition of
NO_DBX_FUNCTION_END we had causes it to avoid .stabs symbols that the
assembler cannot handle for a.out. [from JDP]
* The previous "EXCEPTION_SECTION_FUNCTION" is the wrong name for EGCS.
It also needed tweaking for EGCS. [from JDP]
Also bump __FreeBSD_cc_version to 400002 in case we need to know we are
using EGCS at some point.
Don't exclude directories that the linker is "known" to search (/lib
and /usr/lib) when deciding whether to pass certain paths to the
linker. Under FreeBSD, the linker is actually known to never search
/lib and to only search /usr/lib in the elf case. Not passing the
paths causes at best causes confusing differences for cross compiling.
This change is conditional on FREEBSD_NATIVE but should be absolute.
