Re: [PATCH] support arm-nacl-compatible ARM-ARM veneers

Hi Roland,

This makes the arm-nacl backend of BFD ld use NaCl-compatible code for the
veneers used for ARM calls with caller and callee PC more than 32MB apart.

	(elf32_arm_stub_long_branch_arm_nacl_pic): New variable.
	(arm_build_one_stub): Increase MAXRELOCS to 3.
	(arm_type_of_stub): Use them if GLOBALS->nacl_p.
	(struct elf32_arm_link_hash_table): Give add_stub_section member's
	pointee type a third argument.

Note - in the future please could you provide patches like this as an attachment ? My mailer applied word-wrap formatting to the patch which made it very hard to apply...
