libselinux: PCRE_LDFLAGS is actually LDLIBS

>From Make's manual:

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the
linker, ‘ld’, such as -L. Libraries (-lfoo) should be added to the
LDLIBS variable instead.

LDLIBS
Library flags or names given to compilers when they are supposed to
invoke the linker, ‘ld’. Non-library linker flags, such as -L, should go
in the LDFLAGS variable.
