[m-dev.] errors from mmc script when compiling srcdist

[Julien Fischer]

Hi,

Building the source distribution for rotd-2023-10-16 onwards results in
a lot of messages from the mmc script about mercury_compile not being
found (which it wouldn't be as it doesn't exist when compiling the
source distribution).

I suspect some of the recent changes to mmake may have inadvertently
broken something.

Julien.
