[FFmpeg-devel] [GASPP PATCH] Don't mangle .L local labels for ELF targets

[Martin Storsjö]

This fixes building FFmpeg's libavcodec/aarch64/h264idct_neon.S
for a Linux target. (It's not necessary to use gas-preprocessor for
such a target for a very long time, but it can be useful to be able
to test gas-preprocessor there still.)
