libgomp: Fix up -static -fopenmp linking [PR109904]
When an OpenMP program with target regions is linked statically,
it fails to link on various arches (doesn't when using recent glibc
because it has libdl stuff in libc), because libgomp.a(target.o) uses
dlopen/dlsym/dlclose, but we aren't linking against -ldl (unless
user asked for that). We already have libgomp.spec so that we
can supply extra libraries to link against in the -static case,
this patch adds -ldl to that if plugins are supported.

* configure.ac (link_gomp): Include also $DL_LIBS.
