[PATCH libxtrans v2] configure: Also add -D_DEFAULT_SOURCE to .pc cflags to shut up glibc warnings

[Hans de Goede]

The latest glibc considers _BSD_SOURCE deprecated, leading to the following
warning being issued for pretty much every C-file in the xserver:

In file included from /usr/include/stdint.h:25:0,
                 from /usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/stdint.h:9,
                 from ../include/misc.h:81,
                 from miexpose.c:82:
/usr/include/features.h:145:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
 # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
   ^

I've discussed this with the glibc developers and the prefered way of fixing
this is by also defining _DEFAULT_SOURCE which is the new way of stating
_BSD_SOURCE / _SVID_SOURCE .
