 	src/lib/libm: Makefile
 
 Log Message:
 Default our libm to -frounding-math, if built with GCC.
 
 The long-standing GCC default is to not respect rounding mode.
 it looks like GCC 7 optimizes rint to a builtin, causing our few
 rounding mode tests to fail.
 
 Fixes PR port-amd64/54000: FP tests failing on amd64 since gcc7 import
