[Bug bootstrap/18422] configure scripts run incredibly slow when bootstrapping on AIX

When AIX Bourne Shell is used for GCC bootstrap, bootstrap is extremely slow due
to the interaction between the configure script and the shell.  To speed up the
process one has to use Bash.  The AIX-specific installation notes mention this:

http://gcc.gnu.org/install/specific.html#*-ibm-aix*

If using Bash did not help, then CONFIGURE_SHELL probably was not set early
enough.  One either needs to define CONFIGURE_SHELL to Bash in a clean build
directory before configuring GCC or one needs to invoke "make bootstrap" with
both SHELL and CONFIGURE_SHELL set to Bash.  Once GCC has been configured, it
remembers /bin/sh in many locations and CONFIGURE_SHELL will not override the
memory.
