Bug 281182: www/firefox needs a rustix/src/backend/libc/fs/syscalls.rs patch
analogous to the one under lang/rust/files/armv7/
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=281182



--- Description ---
For rust 1.79.0_1 vs. firefox 129.0.2_2 , the only difference needed
for the content of the patch files was the file path:

# diff
/usr/ports/lang/rust/files/armv7/patch-vendor_rustix_src_backend_libc_fs_syscal
ls.rs
/usr/ports/www/firefox/files/patch-third__party_rust_rustix_src_backend_libc_fs
_syscalls.rs

But rust and firefox have progressed since then. However, a similar point
may well apply to the updated pair.

This will mat†er if someone ever tries to get armv7 firefox to build
(and work): This appears to be one of multiple things that are broken
for that context, one I happen to have figured out via a suggestion
someone made on a list.
