#	$(call build,FOO,$filename,\
#		foo -flags $filename \
#	)

# Generate a library .a file from a list of object files.
# For consistency of symbol ordering, we do not use ar to do any
# updates of the library, but instead remove the old one and
# re-generate it from all of its input object files.

# Typical usage:
#	$(call buildlib,libfoo.a,$(FILES))
