# This is the target specific configuration file. This is invoked by the
# autoconf generated configure script. Putting it in a separate shell file
# lets us skip running autoconf when modifying target specific information.
# This file switches on the shell variable ${target}, and sets the
# following shell variables:
# config_path An ordered list of directories to search for
# sources and headers. This is relative to the
# config subdirectory of the source tree.
# XCFLAGS Add extra compile flags to use.
# XLDFLAGS Add extra link flags to use.
# Optimize TLS usage by avoiding the overhead of dynamic allocation.
# This does require that the library be present during process
# startup, so mark the library as not to be dlopened.
