bpfilter: check if $(CC) can link static libc in Kconfig
On Fedora, linking static glibc requires the glibc-static RPM package,
which is not part of the glibc-devel package.
CONFIG_CC_CAN_LINK does not check the capability of static linking,
so you can enable CONFIG_BPFILTER_UMH, then fail to build:
HOSTLD net/bpfilter/bpfilter_umh
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
Add CONFIG_CC_CAN_LINK_STATIC, and make CONFIG_BPFILTER_UMH depend
on it.
