Fix compile time warning in tc-xtensa.c

Fix compile time warning in tc-xtensa.c

[Nick Clifton]

Hi Guys,

  I am checking in the patch below to fix this compile time warning
  message encountered whilst building the xtensa toolchain:

    .../config/tc-xtensa.c: In function `get_aligned_diff':
    .../config/tc-xtensa.c:8194: warning: comparison between signed and unsigned

  Cheers
    Nick

	* config/tc-xtensa.c (get_aligned_diff): Change type of
	branch_align to offsetT so that its signedness matches that of
	target_size.
