Notes:
This is a utilty script for help with the MISRA process.
This script matches all linker symbol names in linker script files for
arm or x86.
Not included are symbol names starting with "." or symbol names enclosed
in quotes since the files dont't use any. The regular expression also does
not match for "&=" and similar compound assignments.
