As mentioned on various Linux distributions, you have to install a
python2-devel
package. The gdb check is here:

https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=gdb/configure.ac;h=6b4b0fa85109d1e0d0a1610fece2ce13295befb9;hb=HEAD#l674

This has been a common issue long enough that Chris moved gdb to one of the
first things built so the error would stop a build near the beginning
rather than after
building gcc.

In a perfect world, sb-check would know how to check for the libraries
needed
which is mostly python2-devel and zlib-devel.

Same for alternative Linux distributions and other BSD variants. There are
just
too many for the core developers to include in their testing. This is where
the
community has to step up if someone cares.

I develop on CentOS but test on CentOS, Ubuntu, and FreeBSD. I try
to visit Windows (Cygwin and MinGW on occasion. Other core developers
have their test OS set. In total, we cover a pretty wide swath but there
are so many we don't hit. But none of us test on Mint or NetBSD and
AFAIK there are not regular reports from Debian.even though Ubuntu should
be close.

I should end by saying that if a host is important, there are the options of
testing it yourself or supporting a core developer add it to their set. It
just
takes time and resources to test a host.

My recent BSP build sweeps have taken 42-48 hours on an 8-core Xeon.
My regular check of build all tools, run bsp tester, and then build bsps and
test on simulators takes from 20 to ~48 hours depending on the computer.
Nice weekend job for someone's computer if you can't decicate a computer
to the task.
