28dec004c0 Do some things to make -ffunction-sections work better. 
* 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.

e286b0bbc0 Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout.
