Patch rtems-rc-20000627-1 from Ralf Corsepius <corsepiu@…>
that is part of the multilib/gnu-canonicalization movement:
Changes:
- New m4-macro: aclocal/multilib.am
- Suppress multiprocessing if --enable-multilib is given to
configure
Notes:
For now this patch only suppresses multiprocessing if
--enable-multilib is given to configure and should not have any
other side-effects, ie. it works around a minor issue which prevents
introduction of multilibs in general.
The RTEMS_ENABLE_MULTILIB_MASTER macro is the core part to build
real multilibs, but can not be applied before other multilib related
issues with RTEMS have been solved. (e.g. sptables.h, bsp_specs,
Cygnus/Gnu? canonicalization, _RTEMS_version, targopts.h, changing
the installation point/tooldir support, etc.).
