AOCC: Use bash for compiler wrapper

[Thyre]

AOCC 4.2.0 and lower (and flang for AOCC 5.0.0) use compiler wrappers to include the GCC toolchain in the compiler command. The original compilers are renamed, and a shell script is created running exec which passes the original compiler name as an argument.

This however can fail if /bin/sh is used. On Ubuntu 22.04 LTS / Zorin OS 17, using exec -a causes the following error message, which then causes the sanity check to fail:

$ exec -a "echo" echo "Hello World"
sh: 1: exec: -a: not found

To work around this, use /bin/bash instead.
