[Patch] sparc-sun-solaris2.8 (cross) missing PATH_MAX

[Brad Spencer <spencer at infointeractive dot com>]

When compiling a sparc-sun-solaris2.8 cross compiler (on
i686-pc-linux-gnu), I encountered the following:

/hosts/bubbles/spencer/devel/gcc340/gcc-3.4.0/sparc-sun-solaris2.8/build-gcc/gcc/xgcc

I vaguely remember seeing this before, and I may have forgotten to
work up a patch.  If you look in <limits.h> on sparc-sun-solaris2.8,
the (only) definition of PATH_MAX is wrapped with the following guard,
which is not active when compiling gmon-sol2.c.

#if defined(__EXTENSIONS__) || __STDC__ - 0 == 0 || \
        defined(_POSIX_C_SOURCE) || defined(_XOPEN_SOURCE)

Rather than risk turning one of those on and affect the result of the
build somehow, I elected to put a "fallback definition" inside
gmon-sol2.c.  A patch is attached.
