Summary:                    Can't link a shared library with cc on HP-UX
Description: 
Bootstrapping 2.8.8 on HP-UX 11.00 with the vendor compiler fails with

[...]
Linking C shared module libcmsysTestDynload.sl
cd /tmp/cmake-2.8.8-test/_build-cc/Source/kwsys &&

For one, that -b needs to be a -Wl,-b. If I do the compiler invocation that way,
I get

host:/tmp/cmake-2.8.8-test/_build-cc/Source/kwsys$ /opt/ansic/bin/
cc +Z -Ae +DA2.0 +ESlit +w1 -z -Wp,-H262144 +O2 -Wl,-E,+nodefaultrpath -Wl,-b -L

/usr/ccs/bin/ld: CODE_ONE_SYM fixup to non-code subspace in file
/opt/langtools/lib/crt0.o - shared library must be position independent. Use +z
or +Z to recompile.


Adding -v to that gives me

cc: NLSPATH is /opt/ansic/lib/nls/msg/%L/%N.cat:/opt/ansic/lib/nls/msg/C/%N.cat:
cc: CCOPTS is not set.
cc: INCLUDIR is INCLUDIR=/usr/include

I don't know how crt0.o is getting in there, but if I invoke ld directly without
that, the link works. There is probably an option that can be given to cc(1) so
that it doesn't pass crt0.o to the linker, but I'm not seeing anything along
those lines in the man page...
