bpftool: Add missing quotes to libbpf bootstrap submake vars

Browse source

When passing compiler variables like CC=$(HOSTCC) to a submake
we must ensure the variable is quoted in order to handle cases
where $(HOSTCC) may be multiple binaries.

For example when using ccache $HOSTCC may be:
"/usr/bin/ccache /usr/bin/gcc"

If we pass CC without quotes like CC=$(HOSTCC) only the first
"/usr/bin/ccache" part will be assigned to the CC variable which
will cause an error due to dropping the "/usr/bin/gcc" part of
the variable in the submake invocation.

This fixes errors such as:
/usr/bin/ccache: invalid option -- 'd'
