you can do:

This actually builds the tarball, then untars it, configure/compile
the untarred source code and launches the regression checks from
there.
Here, "make distcheck-fast" is a variant of the standard "make distcheck".
It compresses with "--fast" instead of default "--best", and is
significantly faster, given the size of the distribution. You very likely
want to use that one for local regression testing.
You can also launch this in parallel by doing:
make -jN -lN distcheck
make -jN -lN distcheck-fast
with N being the number of processor core you have on your system.

A variant of distcheck is "make distcheck-fast". It's like "make
distcheck" but it's faster. You can just use that one.
A complementary regression checking target is "check-self-compare".
You invoke it by doing "make check-self-compare". That target
