Fix warnings in coreboot utilities.

- Fix some poor programming practice (breaks of strict aliasing as well
  as not checking the return value of read)
- Use PRIx64 instead of %llx to prevent compilation warnings with both
  32bit and 64bit compilers
- Use same compiler command options when linking inteltool and when
  detecting libpci for inteltool
