Commit: ld: Add ability to print hex values in the linker map

[Nick Clifton]

Hi Guys,

  Whilst working on an enhancement to the linker map output I found it
  frustrating that I could not print hex values that were not addresses,
  so I am applying the patch below.  It adds support for "%x" and "%lx"
  to the formats allowed with the vinfo() function.

Cheers
  Nick
