Hi, Mark,

Thanks for testing!

‘configure’ says:

This check comes from libtool.m4.  It has specific cases for other
platforms, but not mips*-*gnu:

--8<---------------cut here---------------start------------->8---
# Some flags need to be propagated to the compiler or linker for good
# libtool support.

  # Find out which ABI we are using.
  echo 'int i;' > conftest.$ac_ext
  if AC_TRY_EVAL(ac_compile); then
    case `/usr/bin/file conftest.o` in
      *32-bit*)
	case $host in

However I don’t see exactly where ‘-m elf’ comes from.

Are you doing a chroot build?  (In which case /usr/bin/file is
unavailable.)

Thanks,
Ludo’.
