If I do: lib_LIBRARIES = libfoo.a libfoo_a_SOURCES = foo.c
in the Makefile.am, libfoo.a will be installed into $(prefix)/lib. If I am using AC_CANONICAL_SYSTEM in configure.ac, I want to be able to set build, host, and target for building a cross compiler. I would then want the above library to be installed into $(prefix)/$(host)/lib. How do I accomplish that?
