That can happen pretty easily if one starts moving libraries.
Better to take backups before this, document what's been moved
and prepare for reflash.

Personally I wouldn't move any executable code (binaries or libs)
on MMC as its contents can corrupt when their file systems get uncleanly
umounted (if you remove the MMC when it's written, disconnect USB
cable without synching the MMC file system or device HW watchdog reboots
the device when there's some unwritten MMC data).

With data files, such as ones in MyDocs or /usr/share/osso-help/
this is a bit more safe.
