[OE-core] [PATCH] do not pass CFLAGS to gcc while building libcap

[jackie.huang at windriver.com]

From: Jackie Huang <jackie.huang at windriver.com>

During do_configure(), we modify the BUILD_CFLAGS used
but do not remove the default inclusion of CFLAGS
in BUILD_CFLAGS.  This fix removes CFLAGS inclusion
by modifying do_configure().
