[aarch64-port-dev ] RFR: Minor infelicity in cross_configure script

[Edward Nevill]

Hi,

The 'cross_configure' script tries to execute bash as '/usr/bin/bash'. 
Of course, on Ubuntu it is '/bin/bash' and may differ on other distros.

Also I believe 'sh' is the correct thing to use, rather than 'bash'.

Patch below fixes.

All the best,
Ed.

bash hardcoded to /usr/bin/bash
