[COMMITTED PATCH] cast Booleanish expression to int when used in switch

[Roland McGrath <mcgrathr at google dot com>]

Committed as obvious enough, to trunk and 2.24 branch.
(Clang warns about this by default.)


Thanks,
Roland

	* elf64-alpha.c (elf64_alpha_relax_tls_get_addr): Cast switch
	expression to int to silence over-eager compiler warnings.
