#72367: openh264 @ 2.6.0 +universal won't compile in apple silicon
-----------------------+----------------------
 Reporter:  AlexVaq    |      Owner:  (none)
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.10.5
 Keywords:  universal  |       Port:  openh264
-----------------------+----------------------
 Compilation fails since the compiler tries to compile specific assembler
 files for ARM64 as universal (with both -arch arm64 -arch x86_64 flags).
 Removing the -arch x86_64 flag allows meson to move forward with the
 compilation, but the linker fails complaining about missing symbols, since
 the x86_64 assembler files are never added to the build.

 A small piece of the log file, when the error happens (it's kilometric,
 since it complains for EVERY assembler mnemonic), including the command
 executed for compilation (notice both arch flags):
