Summary: Configure uses GNU ld flags with non-GNU compilers/linkers

Initial Comment:
I was just attempting to build Python 2.3.4 on Solaris 9, using 
Sun's Compilers and linkers (/opt/SUNWspro/bin/cc and /usr/ccs/
bin/ld).
The configure script correctly determined that I was not using 
either GNU gcc or GNU ld. However, it continued to put GNU 
specific variables into the Makefile (specifically, -Wl,<stuff>).  This 
broke several things, until I manually removed them. The first 
place it broke was when it created the shared library, which, 
because of the different ways that Sun's linker and GNU ld handle 
options, ended up being named "name\=libpython2.3.so.1.0" 
because Sun's compiler detected two -o flags (the first being in the 
-Wl,-soname=libpython2.3.so.1.0 -o libpython2.3.so.1.0) - and 
Sun's linker takes the first -o flag it sees (it helpfully tells you that, 
though).
So... the GNU specific flags need to ONLY be used if the GNU ld/
gcc are being used.

Verified that this works with the Sun PRO C compiler on
Solaris 2.6 and Solaris 8.

I'm a bit surprised that you are saying that the C compiler
has problems with -Wl, options. Atleast in "Sun WorkShop 6
update 1 C 5.2 2000/09/11", the -Wl option is documented for
cc, and works fine.

Instead, it appears that the system linker does not support
the -soname option.

However, this option is only used if you build with
--enable-shared, which apparently is supported only for GCC
on Solaris. So as a work-around, don't use that option.

I have now replace -shared with -h in Makefile.pre.in
1.136.6.5 and 1.148, which should fix this bug. Since I
don't have SunPRO, I cannot test that scenario.
