# PD_CHECK_UNIVERSAL([VARIABLE-NAME], [ACTION-IF-SUCCESS], [ACTION-IF-NO-SUCCESS])
# will enable the "--enable-universal=<ARCHS>" flag
# if <ARCH> is "yes", platform defaults are used
# the system tries to build a test program with the archs, on succes it calls ACTION-IF-SUCCESS, and ACTION-IF-NO-SUCCESS otherwise
# on success it will also add the flags to:
# [VARIABLE-NAME]_CFLAGS will hold a list of cflags to compile for all requested archs
# [VARIABLE-NAME]_LDFLAGS will hold a list of ldflags to link for all requested archs
