Allow clearer suppression of toolchain and compiler prefixes
Currently it is counterintuitive to disable toolchain prefixes: we need
to pass an empty space to it; passing an empty string would not disable
prefixes but instead instruct the build script to use a set of default
prefixes.
With this patch we restore the intuitive approach of passing an empty
string "" to disable the prefix.
Resolves COMPMID-5353, COMPMID-5380
