Stefan Weil f8b72754c2 Move macro QEMU_GNUC_PREREQ to compiler.h 
The macro is compiler specific and does not depend on the operating system.

Move macro QEMU_GNUC_PREREQ from osdep.h to compiler.h
and use it to simplify existing code.

host-utils.h uses this macro, so it now needs compiler.h
instead of osdep.h.

balrog c89068455d Include <strings.h> for ffs(). 
ffs() is in <strings.h> although bsd compatible systems have it in
<string.h> already.  ffs() is used in omap1.c, omap2.c, omap_i2c.c,
bt-sdp.c.  These uses can be replaced with clz32() but ffs is more
available.  Problem was spotted by malc.

Make host-utils.h formatting more consistent.
