Summary: configure changes for Solaris

Initial Comment:
Configure was setting gcc -shared to build shared libraries on SunOS. Changed it back to gcc -G. The -shared option does not work on Solaris

I'm sorry to see this patch backed out, since it solves my
problem.  I'm using SunOS 5.6 with gcc 2.8.1.  When gcc
-shared tries to link against .a files, I get a slew of
errors such as:
[...]
<unknown>            0x94   /usr/local/lib/libz.a(deflate.o)
<unknown>            0xa0   /usr/local/lib/libz.a(deflate.o)
<unknown>            0xac   /usr/local/lib/libz.a(deflate.o)
ld: fatal: relocations remain against allocatable but
non-writable sections
WARNING: building of extension "zlib" failed: command 'gcc'
failed with exit status 1

These messages, and the error, goes away when using gcc -G.

Since Scott did not provide any rationale or indication of a
problem being solved with this patch, I'll reject it.

Message:
Why was this patch approved? Why does the -shared option not work on Solaris? -shared does the following things:
- invoke the linker with -G -dy -z text (the latter only if -mimpure-text was not given)
- drop crt1.o from the list of objects being linked
- drop -lc from the list of libraries being linked
OTOH, -G is just passed through to the linker.

The things that -shared does are necessary: crt1.o defines _start, and requires main, so it should not be present in a shared library. Likewise, -z text should be used to detect position-dependent code at compile time.

Unless some explicit rationale can be given, I think this patch should be reversed.
