Subject: [PATCH 2/7] BaseTools/header.makefile: remove "-c" from BUILD_CFLAGS

Message-id: <20180829151204.26958-3-lersek@redhat.com>
Patchwork-id: 81964
O-Subject:  [RHEL8/virt212 edk2 PATCH 2/7] BaseTools/header.makefile: remove "-c"
	from BUILD_CFLAGS
Bugzilla: 1607906
Acked-by: Thomas Huth <thuth@redhat.com>

Option "-c" is a mode selection flag (choosing between compiling and
linking); it should not be in BUILD_CFLAGS, which applies only to
compiling anyway. The compilation rule for C source files, in
"footer.makefile", already includes "-c" -- currently we have double "-c"
options.

This patch doesn't change behavior.
