libtool: opt_duplicate_compiler_generated_deps is harmful on Solaris
Fix for http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16452.
* build-aux/ltmain.in (libtool_validate_options): disable the
opt_duplicate_compiler_generated_deps optimization for Solaris2 so
that gcc-4.9+ compiled C++ code with -Wl,-Bdirect on 64-bit Solaris
x86 can avoid unwinding failures caused by accidental mixing of the
libc and libgcc_s unwinders in a single executable.
