libgomp: Define config_path for hppa*-*-linux*

[thirdparty/gcc.git] / libgomp / configure.tgt

# 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.
#  tmake_file		A list of machine-description-specific
#			makefile fragments.

# Optimize TLS usage by avoiding the overhead of dynamic allocation.
