sudo: set CFLAGS for build mksigname and mksiglist
mksigname and mksiglist are compiled by BUILD_CC for build host. When
there are some options in CFLAGS that BUILD_CC doesn't support,
compilation fails.
Build for arm on a x86 host, if option "-mapcs-frame" is provided, error
occurs with:
| cc1: error: unrecognized command line option "-mapcs-frame"
Pass BUILD_CFLAGS to CFLAGS to fix that kind of failure.
