cppdefault.c If CROSS_DIRECTORY_STRUCTURE is defined, don't use the native
system header dir; use CROSS_INCLUDE_DIR instead if it is defined.
This just makes GCC's behavior match the documentation for the
"--with-sysroot" configure option, which corresponds to
TARGET_SYSTEM_ROOT. The documentation says that if you specify
directories with --with-sysroot and --with-native-system-header-dir,
then the compilter will concatenate the the two together (with the
sysroot coming first) and search that directory instead of the default
/usr/include.
The concatenation is done with this line in configure.ac:
CROSS_SYSTEM_HEADER_DIR='$(TARGET_SYSTEM_ROOT)$${sysroot_headers_suffix}$(NATIVE_SYSTEM_HEADER_DIR)'
Then Makefile.in sets the preprocessor macro CROSS_INCLUDE_DIR equal to
CROSS_SYSTEM_HEADER_DIR.
This patch reverts one of the changes from Daniel Jacobowitz on 2013-02-13.
