Do some things to make -ffunction-sections work better.

Browse source 
* Add wildcards to various sections placements a la *(".text") => "*(.text*)"
* Remove hacky bits from those linker scripts (no problem encountered testing)
* Change section for asm functions from .<section> to .<section>.<function>
  so that -ffunction-sections works for those asm file too.
