Kang Kai (1):
sudo: set CFLAGS for build mksigname and mksiglist

1.7.5.4

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.
