# Generate additional MCU-specific linker scripts by using the
# default PRU-LD linker script.
#
# We do it automatically so that:
# 1. We only change the default linker script in binutils.
# 2. All the default script complexity stays in binutils.
# 3. Here in libgloss we only bump the memory sizes to
# allow large test programs to be executed.
