"""
PlatformIO doesn't natively link .o files vendored inside a library directory.
The Morse Micro SDK ships the chip firmware (mm6108.mbin.o) and per-region BCF
(bcf_mf08651_us.mbin.o) as pre-built object files containing data sections.
This script appends them to LINKFLAGS so they land in the final ELF.

US region only for now — when we add EU/JP/KR variants, gate the BCF here on a
build flag and pick the matching .o file.
