# Bosch has a goof in their PlatformIO packaging making linking fail.
# The BSEC library's extra_script.py selects cortex-m4/libalgobsec.a (soft-float ABI).
# nRF52840 compiles with -mfloat-abi=hard, requiring the fpv4-sp-d16-hard blob.
# Workaround to prepend the hard-float path so the linker finds it before the
# soft-float one.
