gst-plugins-base: fix rare but annoying build errors

As mentioned long ago in [1] for me gst-plugins-base failed when rebuilding.
Before this patch I had no other choice but to build from scratch.

When error occured I saw

in config.log:
GLIB_CFLAGS='-pthread line /home/superandy/tmp/oe-core-glibc/sysroots/raspberrypi2/usr/include/glib-2.0 -I/home/superandy/tmp/oe-core-glibc/sysroots/raspberrypi2/usr/lib/glib-2.0/include'

and build failed with:
| arm-angstrom-linux-gnueabi-gcc: error: line: No such file or directory
