Dear Maintainer,

Firefox is failing to build with a mountain of errors that start with:

See the buildd log https://buildd.debian.org/status/fetch.php?pkg=firefox&arch=armhf&ver=127.0.1-1&stamp=1718848469&raw=0

This does *NOT* happen with binutils 2.42-4 from testing.

I'm attaching the preprocessed assembly file that triggers the problem.

Command line: as --gdwarf-5 -march=armv7-a+fp -mfloat-abi=hard -meabi=5 --noexecstack -o pixman-arm-simd-asm.o pixman-arm-simd-asm.s

as confirmed by binutils upstream, this should be fixed in firefox.
