Add a -v to the compiler options, and it will tell you the exact
linker command line it's using.  That should indicate where it is
searching for these files.

It's somehow a problem with that particular toolchain build, albeit I
don't have the faintest idea /what/ went wrong.  Hmm, one idea just
comes to mind: the compiler and library disagree about whether these
MCU types belong into either of "avr5" or "avr51" categories.  IMHO,
this can only happen if the library is built using a different
compiler than the compiler you've installed.

For an up-to-date Linux toolchain with a decent patchlevel, I'd
recommend using Bingo600's Linux build script:
