I was slightly mistaken about the purpose of build-essential.  After
checking the description I now see that it is needed for building Debian
packages.  For arbitrary C programs it should be enough to install gcc
and libc6-dev.

You're absolutely right, but there's more than one implementation of the
standard C library (libc6, dietlibc, klibc, probably more).  And there
are also programs (like the Linux kernel) that do not use the standard C
library.

Cross compiler?  I doubt it.  "Cross compiler" means a compiler that
produces executables for a different platform.  What you got is a C++
compiler.
