Because it creates less problems than the alternatives. There is a lot
of code in the wild that essentially assumes a random version of gcc for
a lot of code. Given that Clang is implementing almost all the GCC
extensions of GCC 4.2.1, it claims to be that version. It means a bit
more work for newer code, but avoids breaking a lot of older code.

Create a bug report against glibc.
