[Qemu-devel] [PATCH] qemu-iotests: Remove PERL_PROG and BC_PROG

[Qemu-devel] [PATCH] qemu-iotests: Remove PERL_PROG and BC_PROG

[Kevin Wolf]

We test for the presence of perl and bc and save their path in the
variables PERL_PROG and BC_PROG, but never actually make use of them.
Remove the checks and assignments so qemu-iotests can run even when
bc isn't installed.

Then we should drop _readlink which is unused and uses perl too. Whether in this
patch together or in a separate patch doesn't matter much, so:

The bc part is nice!
