Subject: [PATCH] configure: add --with-bash option for cross-compilation

AC_PATH_PROG finds bash on the build host, which differs from the
target system path in cross-compilation environments. Add
--with-bash=PATH to allow explicitly specifying the bash path on
the target system.

When not specified, the existing auto-detection behaviour is
unchanged.
