[Unbound-users] [PATCH] update pthreads detection macro

[Robert Edmonds]

hi,

the attached patches update the pthreads detection macro to the latest
upstream autoconf-archive version (see [0] for changes; btw, the macro
has been renamed from ACX_PTHREAD to AX_PTHREAD), and additionally fix a
false negative in the detection logic when "-Werror" is added to CFLAGS
(see [1] for details).
