Hi, I recently updated libffi, libatomic_ops, and libgc on core-updates. Unfortunately, all three of them fail on MIPS, for the same reason that sudo and gawk currently need workarounds: all of these packages were bootstrapped with a version of 'libtool' that requires /usr/bin/file on MIPS.
Given that this problem is becoming increasingly common, I think we should add 'file' as an implicit native-input for the gnu-build-system in core-updates, and also add a new phase to %standard-phases that substitutes /usr/bin/file in the usual places with a path that works in the build environment. What do you think? Mark
