Seems to resolve text relocation issues on aarch64.
Thanks to an upstream commit fixing the exact problem we're having
(on Linux...) from 2014 for the hitn...
Bump PKGREVISION.
multimedia/ffmpeg4 does not need -std=gnu99, only ffplay4 does.
Since mk/compiler.mk is protected by a multiple-inclusion guard, any
later assignment to USE_LANGUAGES has no effect except being confusing.
The additional languages show up in "bmake show-var" but at the point of
evaluation, they had not been set yet.
This can be detected by several pkgsrc tools:
pkglint says:
WARN: ../../multimedia/ffmpeg4/Makefile.common:14: Modifying
USE_LANGUAGES after including ../../mk/compiler.mk has no effect.
Adding a manual check to mk/compiler.mk results in:
bmake[1]: "mk/compiler.mk" line 273: warning:
For multimedia/ffmpeg4, only languages "c" are used,
the others in "c99" were defined too late.
Making the variable USE_LANGUAGES read-only after including
mk/compiler.mk results in:
bmake[1]: "multimedia/ffmpeg4/Makefile.common" line 14:
Read-only USE_LANGUAGES cannot be set
(The latter two checks are not yet in the official pkgsrc tree.)
