# We're building a single .a file from files in several
# subdirectories.  We use the "single Makefile, multiple subdirectory"
# automake alternative. We're doing this because we're faking out
# automake and getting it to build for 2 architectures at the same
# time, the PPE (powerpc64) and the SPE.  The easiest way to handle
# the SPE was to just build a static library using automake's built in
# rules, since trying to get libtool to handle two architectures in
# the same tree seemed untenable.
