[Bug c/43974] New: Undefined symbol main in crt1.o when compiling shared libs on Solaris

["bjoern at j3e dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Comiling any shared library on Solaris with LDFLAGS "-Wl,-z,defs" to make sure
that there are no unresoloved symbols results in:

Undefined                       first referenced
 symbol                             in file
main                               
/usr/local/lib/gcc/sparc-sun-solaris2.10/3.4.6/crt1.o
ld: fatal: Symbol referencing errors. No output written to bin/libtalloc.so.2

It looks like there is a wrong assumption about a shared library having to have
a symbol "main" on gcc on Solaris. More recent gcc releases than the above
example are also affected.
