[PATCH] apr_cv_mutex_recursive=yes added to apr_1.4.6.bb to make rosnodes work

[vmayoral <v.mayoralv@gmail.com>]

From: victor <v.mayoralv@gmail.com>

Working with the meta-ros project we detected that the ROS nodes didn't launch properly
the reason was that by default apr_cv_mutex_recursive in apr is set to no and this leads
to the APRENOTIMPL return value of apr_thread_mutex_create in thread_mutex.c when
APR_THREAD_MUTEX_NESTED is requested via flags.

Added CACHED_CONFIGUREVARS += "apr_cv_mutex_recursive=yes" to sources/openembedded-core/meta/recipes-support/apr/apr_1.4.6.bb
to fix this issue. It has also been removed the mention of this variable in
meta/site/powerpc32-linux.
