System: NetBSD arnold 11.99.1 NetBSD 11.99.1 (EGGHED64) #5: Sun Aug 24 07:07:16 UTC 2025 mlelstv@slowpoke:/home/netbsd-current/obj.evbarm64-el/scratch/netbsd-current/src/sys/arch/evbarm/compile/EGGHED64 evbarm
Architecture: aarch64
Machine: evbarm
>Description:
On aarch64, maybe elsewhere, The last pullup to pkgsrc-2025Q2 broke
the palemoon package.

It fails in the install stage because libmozavcodec.so and libmozavutil.so
are built but are not in the PLIST. The PLIST has only conditional entries
for these files:

${PLIST.ffvpx}lib/${PKGNAME}/libmozavcodec.so
${PLIST.ffvpx}lib/${PKGNAME}/libmozavutil.so

and the Makefile selects this for x86_64 only:

.if ${MACHINE_ARCH} == "x86_64"
PLIST.ffvpx=            yes     # see platform/old-configure.in
.endif

>How-To-Repeat:
Build palemoon on aarch64.
>Fix:
Enabling PLIST.ffvpx for aarch64 fixes the build, but maybe other
archs are also affected.
