Cortexm-common ldscript

This test checks the support for building firmwares with a rom offset and specific sized firmwares using cortexm-common ldscript.

When building all, the compile-tests target is also build and executes build time compilation tests checking different firmwares configurations verified by inspecting the result elf files.

Test output

For a board that does not have a ROM_OFFSET variable configured by default (== a board without bootloader installed), it produces the following output after the normal compilation:

make all BOARD=iotlab-m3
...
Test rom offset 1 byte overflow detection: [OK]
Test rom offset subtracted from rom length in elffile: [SKIP](Reason: board does not have a ROM_OFFSET configured)
Test compilation with offset 0x1000: [OK]
Test compilation with offset 0x2000: [OK]
Test compilation with half ROM length: [OK]
Test ROM overflow detection (too_big_for_rom): [OK]
Test ROM overflow detection (offset_and_romlen): [OK]

For a board that have a ROM_OFFSET variable configured by default (== a board with bootloader installed), it produces the following output after the normal compilation:
