Bug 292032 - armv7 on aarch64 (tested chroot, lib32) gets SIGSEGV for the likes of: gpart show [native armv7 kernel use contexts do not get any SIGSEGV's]

The context here is official pkgbase distribution installation usage,
not personal builds. /usr/src/ is from the pkgbase installation, not
git use.

A backtrace from chroot use on aarch64 looks like:

Core was generated by `gpart show'.
Program terminated with signal SIGSEGV, Segmentation fault.
Address not mapped to object.
#0 0x200c5ef0 in delete_config (gp=0x2053c1dc) at /usr/src/lib/libgeom/geom_xml2tree.c:502

warning: Source file is more recent than executable.
502 LIST_REMOVE(cf, lg_config);
(gdb) bt

#4 0x00022308 in main (argc=1, argv=0xffffdc5c) at /usr/src/sbin/geom/core/geom.c:861

Operation of the same armv7 world files in a booted armv7 kernel context
does not get any SIGSEGV's. This is true even using the files from the
same media moved from native use to a chroot usage context on aarch64.
On aarch64, the likes of:

# env GEOM_LIBRARY_PATH=/usr/lib32:/usr/lib32/geom /mnt/sbin/gpart show

also gets a SIGSEGV.

NOTE:
Be warned that inappropriate %ld formatting use was recently fixed and
caused some problems earlier in the execution, including SIGSEGV
behavior. Test with/after 2025-Dec-29's:
