[Buildroot] [PATCH 2/2] wayland: fix musl build issue

[Rahul Bedarkar <rahul.bedarkar@imgtec.com>]

With musl C library, we see following build failure.

  src/scanner.c: In function 'find_enumeration':
  src/scanner.c:811:2: error: unknown type name 'uint'
    uint idx = 0, j;
    ^

uint is defined in <sys/types.h> header. It is usually included by <stdlib.h>
but in musl stdlib.h doesn't include it.

In scanner.c, <expat.h> includes <stdlib.h> then it includes <sys/types.h> in
case of other C libraries. <sys/types.h> from musl defines uint only if
_GNU_SOURCE or _BSD_SOURCE is defined. Instead of including <sys/types.h> and
defining either _GNU_SOURCE or _BSD_SOURCE, use unsigned int instead of uint.

Fixes:
