[Buildroot] [PATCH 1/1] package/x11r7/xlib_libXfont2: disable usage of libbsd

[Bernd Kuhls]

Upstream added optional support for libbsd:
"Add strlcat & strlcpy fallbacks if not provided by libc nor libbsd"
https://cgit.freedesktop.org/xorg/lib/libXfont/commit/?id=d4c941ea8b1dc07a14efce656bff58d31a14c985

In the case that libbsd was built before xlib_libXfont2 it gets picked
up by configure:

checking for library containing strlcat... -lbsd
checking for reallocarray... yes
checking for strlcat... yes
checking for strlcpy... yes

which leads to build errors.

Building without libbsd being built before succeeds:

checking for library containing strlcat... no
checking for reallocarray... yes
checking for strlcat... no
checking for strlcpy... no

Instead of fixing a problem in the xlib_libXfont2 code we disable the
usage of libbsd altogether:

checking for library containing strlcat... (cached) no

and force xlib_libXfont2 to use its internal headers.

Fixes:
