Re: cross-compilation documentation

[Andrew Pinski <pinskia@physics.uc.edu>]

It is documented, just not fully:

"that each --with option has a corresponding --without option"

--with-headers
--with-headers=dir
Deprecated in favor of --with-sysroot.  Specifies that target headers 
are available when building a cross compiler.  The dir argument 
specifies a directory which has the target include files.  These 
include files will be copied into the gcc install directory.  This 
option with the dir argument is required when building a cross 
compiler, if prefix/target/sys-include doesn't pre-exist.  If 
prefix/target/sys-include does pre-exist, the dir argument may be 
omitted.  fixincludes will be run on these files to make them 
compatible with GCC.

Thanks,
Andrew Pinski
