community/firefox: segfaults on arm7

firefox-120.0-r0, postmarketOS Edge on Microsoft Surface RT. firefox-119.0.1-r0 worked fine.

(gdb) bt
#0  0x000206e4 in ?? ()

I assumed this is not related to #15512 (closed) since PGO was already disabled on arm7 before the update to 120.0 and is still disabled. However the strace:

...

... is exactly the same as this comment so maybe the issue is the same and independent of PGO.
