One can give configure an option (see this file), or before running it (in bash):
 export CC=/usr/bin/cc CXX=/usr/bin/c++
CXX is only needed if you do the C++ stuff.

Another tip is to build without the source directory, which is required when building GCC:
 tar -xf <package-distribution>
 mkdir build
 cd build
 export CC=/usr/bin/cc CXX=/usr/bin/c++
 ../<package-sources>/configure

This one is useful when doing several different builds, like trying different compilers, as the package source isn't touched.
