This looks like a compiler bug rather than a problem in Amber. The intel
compilers are notorious for being buggy. You mention that you are using
ifort v8.1 - I have never tried to build amber8 with this version of ifort
so don't know what the problems are. I also can't currently get onto intel's
website to try and download it. However, can you try and get hold of ifort
v8.0 and see if that works, ifort 8.0 is known to compile amber 8.0 fine.

Also, try unsetting MKL_HOME and re-running config and see if you can get it
to compile with the MKL libraries. Also try:

unset MKL_HOME
./configure -p4 -static -nopar ifort

Let me know how you get on.

All the best
