Remove gcc, and keep stdenv. :)
stdenv has the right propagated build input, for you to have gcc in the path.

At the time you refer to 'gcc' in your overrides, you are not referring to the
gcc you want.

First applies packageOverrides ('overrider', in applyGlobalOverrides'), and then
applies the stdenv overrides. So, at the time of packageOverrides, 'gcc' means
'gcc built by stdenv'. When the stdenv overrides apply, *later* (note the //
inside the definition of applyGlobalOverrides), 'gcc' means 'gcc part of
stdenv'.
