Fixes <https://bugs.gnu.org/49113>. Reported by Maxime Devos <maximedevos@telenet.be>. Previously, the cross-compiled libc.so linker script would read: OUTPUT_FORMAT(elf64-little) instead of: OUTPUT_FORMAT(elf64-littleaarch64) This is because glibc 2.33 runs "objdump -f" instead of "aarch64-linux-gnu-objdump -f" to determine the output format. * gnu/packages/patches/glibc-cross-objdump.patch: New file. * gnu/local.mk (dist_patch_DATA): Add it. * gnu/packages/base.scm (glibc)[source]: Use it.

Arrange so that glibc uses 'TRIPLET-objdump -f' rather than 'objdump -f'
|
|
to determine the 'OUTPUT_FORMAT' value in libc.so when cross-compiling.

Patch submitted upstream:
