[FFmpeg-devel] [PATCH] configure: fix assignment of assembler specific flags

[James Almer]

If the first assembler to be probed is an old nasm build, X86ASM_DEPFLAGS
will be set and remain so after yasm is ultimately used as fallback.
This results in yasm being called with said nasm specific flags and failing
during actual object assembly but not with configure sanity checks.

Regression since 5cae5a1defa360da076365a786093a749d1ddf4e
