package/libcap: fix static builds

Browse Source 
Since libcap has been updated to version 2.77 in Buildroot commit
42f2b480a5, the build fails for
statically-linked configurations when the host system doesn't have a
static version of libc installed:

/usr/bin/ld: cannot find -lc: No such file or directory
/usr/bin/ld: have you installed the static version of the c library ?

This is because the -static flag that is supposed to be used when
building target code also gets passed to the host compiler... which is
obviously incorrect and leads to the build failure.

This issue was introduced by upstream commit
c3ddf45d9afaab85d3b7db0dc7bfd1aafb8fde50, which was reverted right
after the 2.77 release in commit
542d7d86ecd2129dd5fe7e5b31ba307304f5b319, which we are simply
backporting here.
