zlib fails to build on sparc solaris 2.7

[Mike Stump <mrs at windriver dot com>]

I was trying to build up a recent cvs pull, and got:

kankakee bash[1018] make

:-(  I have a GNU ld in my path, I configured with:

/kankakee1/tmp/mrs/net/egcs/zlib/configure  --cache-file=../config.cache --host=sparc-sun-solaris2.7 --build=sparc-sun-solaris2.7 --enable-multilib --with-gcc-version-trigger=/kankakee1/tmp/mrs/net/egcs/gcc/version.c --prefix=/folk/mrs/packages/gcc-20001030 --srcdir=../../../egcs/zlib --with-target-subdir=sparc-sun-solaris2.7

I have GNU in my PATH, and it runs Sun's LD from collect2:

It seems a whee bit brittle.
