This step is not _gcc_, it's the C library headers step.

And this one is the C library start files step.

Oh, and by the way, sending only the WARNings is not very usefull. What is,
is the full build.log file.

Look in the code, there is an explanation for this (Hint: search the
code for the glibc headers install step. Hint-2: NPTL is a threading
implementation, as linuxthreads is).
