[Qemu-devel] [PATCH 8/8] configure: do_compiler: Dump some extra info under bash |

This makes it much easier to find a particular thing in config.log.
The information may be lacking in other shells, resulting in harmless
empty output. (This is why we don't use the proper ${FUNCNAME[*]}
array syntax - other shells will choke on that.)
The extra output is only printed if configure is run with bash. The
something), it is necessary to say bash ./configure to get the extra
debug info in the log.
