Yes, although neither is critical at this stage.

So far so good.

First thing to note is that this is an invocation of "gcc", not
"mb-gcc". When the mtd-utils are built, the build system creates host
versions (with gcc), and target versions (in this case with mb-gcc) of
the various tools.
So, the problem realtes to the host build, not target.
Looking at the error, it seems that maybe your host gcc is not happy
with the type uint32_t. On my RedHat 8.0 system, this type is defined
You don't mention what linux distro you are using, perhaps it is
something to do with that? I seem to recall problems a few people had
similar strange host-based building issues under RedHat7.2 - it was
fixed by upgrading to either 8.0 or 9. I think there are also people
now using Fedora core, not sure.
Not an answer yet, but a suggestion of where to go looking!
