[OE-core] [PATCH v1] site: enable pthread support for x86_64 APR builds

[Ioan-Adrian Ratiu]

From: Jacob Champion <jacob.champion at ni.com>

The apache2 package was missing key pieces of pthread support (notably,
pthread_kill) on x86_64 platforms. Fix this by setting some cached
variables that are already set for other targets:

  apr_cv_pthreads_cflags=-pthread: enables pthread support for APR,
  which will trickle down into apache2 as well. powerpc32-linux
  currently sets this option.

  apr_cv_process_shared_works=no: several platforms already set this
  option, which conservatively disables support for PROCESS_SHARED
  mutexes.
