Adding quad float gcc intrinsic implementation for SPARC
Sparc-Gcc generates q_xxx intrinsic calls for quad float ("long double") code. The routines from glibc's glibc-2.9/sysdeps/sparc/sparc32/soft-fp/* where taken and ported to uclibc. Signed-off-by: Konrad Eisele <konrad@gaisler.com> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
