The only significant difference I see is on the collect2 (ld wrapper) 
command line:

Gentoo:
-L/usr/lib/gcc/m68k-atari-mint/4.5.2
-L/usr/lib/gcc/m68k-atari-mint/4.5.2/../../../../m68k-atari-mint/lib

Cygwin:
-L/opt/cross-mint/lib/gcc/m68k-atari-mint/4.5.2/mshort
-L/opt/cross-mint/lib/gcc/m68k-atari-mint/4.5.2/../../../../m68k-atari-mint/lib/mshort
-L/opt/cross-mint/lib/gcc/m68k-atari-mint/4.5.2
-L/opt/cross-mint/lib/gcc/m68k-atari-mint/4.5.2/../../../../m68k-atari-mint/lib

We can see that on Cygwin the mshort libdirs are prepended, while on Gentoo 
they are lost. Everything else is correct.

If I'm not wrong that command line is built by the "gcc" command.

Really, I wonder if Gentoo's multilib support has not been hacked to match 
their guidelines, something like Patrice's patch to avoid mixing different 
multilibs.
I don't say multilib does not work on Gentoo, but maybe it works 
differently, so it may require different patching for MiNT.
