configure: Don't link with -Wl,-z,defs on FreeBSD.
On FreeBSD, using environ
in a shared library linked with -Wl,-z,defs
causes an undefined reference error:
gcc -m64 -o dlls/msv1_0/msv1_0.so -shared -Wl,-Bsymbolic -Wl,-soname,msv1_0.so -Wl,-z,defs dlls/msv1_0/unixlib.o dlls/ntdll/ntdll.so
/usr/local/bin/ld: dlls/msv1_0/unixlib.o: in function `ntlm_fork':
/usr/home/pip/wine/build64/../dlls/msv1_0/unixlib.c:206: undefined reference to `environ'
collect2: error: ld returned 1 exit status
*** Error code 1
This is unfortunately a common issue on FreeBSD, see:
