Try a release build, it needs less disk space and RAM to link.
And unless you intend to cross-compile, try --enable-targets=host-only.

No, shouldn't take hours, it takes 6m 44s here to do a full
debug+asserts build of clang, out of which 1m is spent linking clang.

What version of gcc and binutils are you using?
See http://llvm.org/docs/GettingStarted.html#brokengcc

How much RAM do you have?
