[Buildroot] [PATCH v2] poppler: link with libatomic when needed

Following errors might occur on architectures required to use gcc libatomics:
sparc-buildroot-linux-uclibc/sysroot/lib/libatomic.so.1: error adding symbols: DSO missing from command line

This is often the case for sparcv8 32 bit toolchains.

See 55a9d6d55888b04ec6c476399e5b98a2412995f5 and 03f6e005e6a9617767b24a9026da9477848020cc.
