# @FUNCTION: get_libdir
# @RETURN: the libdir for the selected ABI
# @DESCRIPTION:
# This function simply returns the desired lib directory. With portage
# 2.0.51, we now have support for installing libraries to lib32/lib64
# to accomidate the needs of multilib systems. It's no longer a good idea
# to assume all libraries will end up in lib. Replace any (sane) instances
# where lib is named directly with $(get_libdir) if possible.
#
# Jeremy Huddleston <eradicator@gentoo.org> (23 Dec 2004):
# Added support for ${ABI} and ${DEFAULT_ABI}. If they're both not set,
# fall back on old behavior. Any profile that has these set should also
# depend on a newer version of portage (not yet released) which uses these
# over CONF_LIBDIR in econf, dolib, etc...

# example of this is xorg-x11, where lib32 isnt a supported configuration,
# and where lib64 -must- be used on amd64 (for applications that need lib
# to be 32bit, such as adobe acrobat). Note that this override also bypasses
# portage version sanity checking.
# get_libdir_override expects one argument, the result get_libdir should
# return:

# get_libdir_override lib64

# prep_ml_includes /usr/qt/3/include
