Gcc includes libraries that require access to the standard C library in
order to build.  You must provide the standard C library yourself
somehow.  You have not done this.

If you only want a compiler for building the kernel, then you don't need
any libraries.  In that case, you are already done.  What you have is
good enough to build a kernel.

If you need a complete gcc build, then you will need a C library.  If
you have access to a running ia64-linux system, the easy way to do this
is to copy the IA-64 linux /usr/include and /usr/lib to the x86 machine,
and then configure using --with-headers= and --with-libs= pointing at
the IA-64 header and library directories respectively.

An alternative method is to try to build gcc and glibc in parallel. 
This is not easy.  Offhand, I don't know how to do it, as I have never
tried to do this.

There is no such configure option.  The headers are required, and there
is no way to get around this.

The standard C library header files are missing.
