[PATCH 09/16] src: Use eu-search in nm and findtextrel.

[Mark Wielaard <mark@klomp.org>]

From: Heather McIntyre <hsm2@rice.edu>

	* src/Makefile.am: Add USE_LOCKS condition for -pthread.
	* src/findtextrel.c: Add eu-search.h and remove search.h.
	Change calls of tsearch/tfind to eu_tsearch/eu_tfind.
	* src/nm.c: Likewise.
