[Buildroot] [1/1] make: disable guile support when static linking enabled

[Ryan Barnett]

When building in a static only configuration with guile package
enabled, the following error happens:

 gc_pthread_redirects.h:37:22: fatal error: dlfcn.h: No such file or
 directory
   #   include <dlfcn.h>

The file gc_pthread_redirects.h comes from bdwgc, which gets built
before make in the autobuild test case you're pointing to. This header
file is known to incorrectly include <dlfcn.h>, unless GC_NO_DLOPEN is
specified.

IF GC_NO_DLOPEN is defined, another issue arises due to libguile and
libintl both defining locale_charset.

Thus disable guile support in make when BR2_STATIC_LIBS is set.

Fixes:
