/lib and /usr/lib should always be for o32. > + if test x$with_endian != x; then > + default_mips_endian=$with_endian > + fi install.texi currently says --with-endian is only for SH; you'll need to update the documentation to say what versions of this option are supported for MIPS. Also, t-linux64 uses MIPS_EL = $(if $(filter %el, $(firstword $(subst -, ,$(target)))),el) to determine endianness for Debian multiarch purposes, and I think this will need to change when you allow --with-endian to control the endianness. -- Joseph S.
