[PATCH 08/20] tools: Use PTHREAD_CFLAGS, _LDFLAGS, _LIBS

[Ian Jackson <ian.jackson@eu.citrix.com>]

Replace all literal occurrences of -lpthread and -pthread in Makefiles
by references to PTHREAD_CFLAGS, PTHREAD_LDFLAGS and PTHREAD_LIBS.
These are the new variables set by configure, and currently expand to
-pthread on the compilation and link lines as is required.
