package/x11r7/xlib_libX11: don't require static libc on host

As per: 4645e21913

"For Windows targets, libtool uses a wrapper executable, not a wrapper
script (see [1]), which it compiles with the host compiler.  This
doesn't work when cross-compiling."

Because of this change, builds fail on Linux hosts without a static
libc. This patch reverts this change as we are guaranteed to build in a
Linux environment.
