- Add `-Wl,--gc-sections` to LDFLAGS - Add `-fdata-sections` and `-ffunction-sections` to CFLAGS - Update lpc2387 linker script to keep the isr vector and init sections when garbage collecting. - Keep .ctors and .dtors sections (similar to what binutils default linker script does when building for Linux targets) Signed-off-by: Joakim Gebart <joakim.gebart@eistec.se>
