libtool.m4: Fix postdeps in NetBSD

Browse Source 
commit:c7be1f229 addresses an issue with building C++ modules on NetBSD, by
removing -lgcc_s and -lgcc. This may sometimes not work correctly, depending
on the architecture, as libgcc_s.so and libgcc.a may contain required code to
properly link the shared object. On NetBSD, libgcc.a is compiled with -fPIC
and can be linked to a shared object without any issue.
