[ccan] [PATCH] tap: fix pthread uses

[Kirill A. Shutemov]

From: "Kirill A. Shutemov" <kirill at shutemov.name>

tap expects that HAVE_LIBPTHREAD will be defined, but configurator
doesn't provide it:

ccan/tap/tap.c:49:5: warning: "HAVE_LIBPTHREAD" is not defined [-Wundef]

Lets check for <pthread.h> in configurator and provide HAVE_PTHREAD_H
based on the results.
