How about leaving out the following:
- Use AC_SEARCH_LIBS([pthread_cancel], [pthread]) and AC_CHECK_FUNC([pthread_cancel]) in
  configure.ac. 
- Use @LIBS@ in Makefile.am.

From https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html:
"If action-if-found is not specified, the default action prepends -llibrary to LIBS [...]".

Bart.
