[Xcb] [PATCH libxcb 2/8] autoconf: use the warning variables from xorg

[Gaetan Nadon]

The BASE_CFLAGS variable contains only warnings, just like the XCB
version of CWARNFLAGS. This will result in no changes in the binaries
produced. Xorg was missing -fd for SUNCC so it has been added to util-macros
v 1.18.

Do not get confused with the xorg deprecated CWARNFLAGS variable which
contains an option that is not a warning, -fno-strict-aliasing. This
option, should it be needed, can be added using the XORG_TESTSET_CFLAG
macro.
