Two unreviewed ARM patches

[Richard Sandiford]

Just wanted to ping these two ARM patches:

http://sourceware.org/ml/binutils/2010-12/msg00473.html
Fix undercounting of possibly-dynamic relocs in check_relocs.
(Ignore the bit at the end about a follow-on patch for PIEs;
the current behaviour is correct.)

http://sourceware.org/ml/binutils/2010-12/msg00461.html
Fix a case where possibly-dynamic relocs remain unswept.
