[Bug bootstrap/17601] New: gcc/Makefile.in: Setting up XX_FOR_TARGET does not work

[ralf_corsepius at rtems dot org]

gcc/Makefile.in applies the construct below to setup various XX_FOR_TARGET make
variables:
..
AR_FOR_TARGET = ` \
  if [ -f $(objdir)/../binutils/ar ] ; then \
    echo $(objdir)/../binutils/ar ; \
  else \
    if [ "$(host)" = "$(target)" ] ; then \
      echo ar; \
    else \
       t='$(program_transform_name)'; echo ar | sed -e $$t ; \
    fi; \
  fi`
..

Apparently, this does not work when building a cross compiler (here
sparc-rtems4.7) on FC2/i386:
..
# cd build/gcc
# make
..

`/users/rtems/src/rpms/BUILD/rtems-4.7-sparc-rtems4.7-gcc-newlib-gcc3.4.3newlib1.12.0/build/gcc'

sed: option requires an argument -- e

AFAIS, the $$t in
t='$(program_transform_name)'; echo ar | sed -e $$t ;

expands to an empty string instead of the correct sed pattern, whic causes the
Makefile to break.
