Fixes the build of pkgsStatic.libcap, as it was trying to link to the
dinamic libc. From libcap-2.69/progs/Makefile:
...
ifeq ($(LIBCSTATIC),yes)
LDFLAGS = --static
DEPS = ../libcap/libcap.a
else
# For this build variant override the LDFLAGS to link statically from
# libraries within the build tree. If you never want this, use make
# DYNAMIC=yes . Note, we can't reliably link statically against glibc
# becasuse of https://sourceware.org/bugzilla/show_bug.cgi?id=12491 .
LDFLAGS = -Wl,-Bstatic
LDFLAGS_SUFFIX = -Wl,-Bdynamic
DEPS = ../libcap/libcap.a
endif
