ROMs produced of Pop!_OS 20.10 and Fedora 33 with SDCC 4.0.0 cause uecflash to crash after verifying the block write, leaving the system unbootable until all power is removed to force an EC reset. Sorting object files appears to resolve this issue, creates a smaller binary (~200 bytes from 20.04), and gives up more reproducible builds.
