description:
Add a new file find-libs.mk that can be included by builtin.mk files
to detect the presence of libraries in the base system.

The input variable is BUILDLINK_FIND_LIBS, which is a list of library
names, e.g. ncurses, iconv, etc., that will be sought in the base
system.  BUILDLINK_LIB_FOUND.<lib> is set to "yes" or "no" depending
on the result of the search.

An example use is:

BUILDLINK_FIND_LIBS:= intl iconv
.include "../../mk/buildlink3/find-libs.mk"
# ${BUILDLINK_LIB_FOUND.intl} and ${BUILDLINK_LIB_FOUND.iconv} are now
# either "yes" or "no".
