rtems-rtl for powerpc

[Aleksandr Platonov]

I am currently trying to add support for powerpc in my local copy
(copied some files from netbsd sources into libbsd/include/arch/powerpc
directory, patched rtl-mdreloc-powerpc.c, etc)
But I got the following error at waf -v -v
13:42:09 runner ['/home/pam/trans/rtems_powerpc/gcc-ppc/bin/rtems-ld',
'--base', 'rtld.prelink', '--entry', 'my_main', '--cc',
'/home/pam/trans/rtems_powerpc/gcc-ppc/bin/powerpc-rtems-gcc',
'xa.c.7.o', 'x-long-name-to-create-gnu-extension-in-archive.c.7.o',
'-o', '/home/pam/trans/rtems-rtl/build/powerpc-rtems-mpc5200/x.rap',
'-Wl,-Bstatic']
error: libelf:elf_getdata: .gnu.attributes(xa.c.7.o): Invalid section
descriptor

When I run readelf -a x.c.7.o I have no errors and see the
following .gnu.attributes section information:
Section Headers:
  [Nr] Name              Type            Addr     Off    Size   ES Flg

Is rtems-ld (rtl-host) should be build with some extra flags when target
arch differs with host arch? I have no such error with the same rtems-ld
when running waf command for i386-rtems.

I have updated libelf for rtl-host in my local copy but this does not
help.
