[Bug bootstrap/23131] New: Fixincludes on cross-build is scanning /usr/include

[Bug bootstrap/23131] New: Fixincludes on cross-build is scanning /usr/include

[rearnsha at gcc dot gnu dot org]

A cross-compiler configured with (for example)

.../configure --target=arm-elf --with-headers=.../newlib/libc/include --with-newlib

No-longer builds on some host systems because fixincludes is now scanning
/usr/include rather than the headers specified.

I suspect this is related to the sysroot change.

Here's the relevant bit of the boot log:

(TARGET_MACHINE='arm-unknown-elf'; srcdir=`cd /home/rearnsha/gnusrc/egcs-cross/g
cc; ${PWDCMD-pwd}`; \
  SHELL='/bin/sh'; MACRO_LIST=`${PWDCMD-pwd}`/macro_list ; \
  export TARGET_MACHINE srcdir SHELL MACRO_LIST && \
  cd ../build-i686-pc-linux-gnu/fixincludes && \
  /bin/sh ./fixinc.sh ../../gcc/include \
      )

Since you're not using --with-sysroot or --with-build-sysroot, I'm slightly
surprised.

What is SYSTEM_HEADER_DIR in your generated gcc/Makefile?  Is it
$(CROSS_SYSTEM_HEADER_DIR), $(NATIVE_SYSTEM_HEADER_DIR), or something worse?

I think I see a bug with *native* compilers that use --with-sysroot, but you're
in a cross configuration.  Of course, I'll try it myself and see momentarily.

Thanks!

NATIVE_SYSTEM_HEADER_DIR = /usr/include
# Default cross SYSTEM_HEADER_DIR, to be overridden by targets.
CROSS_SYSTEM_HEADER_DIR = $(gcc_tooldir)/sys-include

# autoconf sets SYSTEM_HEADER_DIR to one of the above.
SYSTEM_HEADER_DIR = 

Ie. it's empty.

I've tested this patch and believe it correct.	I'm running tests in more
configurations now.  I would appreciate if if you could confirm that it fixes
your problem.
