[PATCH] linux-user: Move PRAGMA_DISABLE_PACKED_WARNING to compiler.h

[Warner Losh <imp@bsdimp.com>]

Replace the slightly older version of this in include/qemu/compiler.h
that was commit as part of bsd-user changes with the newer one from
linux-user. bsd-user has no regreassions with this.

- * Tricky points:
- * - Use __builtin_choose_expr to avoid type promotion from ?:,
