I assume you are speaking of a cross-compiler.
The prefix above is good, it is the the standard one. But it looks strange.

The standard rules:

1) The cross-tools are stored in /usr/bin, prefixed with the target prefix.
For example /usr/bin/m68k-atari-mint-as

2) The target development files are stored in /usr/<target>.
For example, /usr/m68k-atari-mint/include, /usr/m68k-atari-mint/lib.

3) There is an additional oddity. GCC requires that 
/usr/bin/m68k-atari-mint-as should be also available as 
/usr/m68k-atari-mint/bin/as as well as some other tools. It is probably 
because GCC always look at an executable named "as" in a directory relative 
to its own executable.
So /usr/m68k-atari-mint/bin contains some cross tools, without prefix. They 
are usually hard links to the prefixed versions.

My Ubuntu binaries use the these standard directories.
My Cygwin packages use /opt/cross-mint instead of /usr to put everything 
related to the cross-compiler into a single directory in order to ease 
uninstallation.

A host library (or executable) which produce target executable files is a 
cross-tool, it should be configured with a /usr prefix. It is the case for 
the binutils and GCC.

However, target libraries intended to be installed on a cross-host should be 
configured with a /usr/m68k-atari-mint prefix. It is the case for the 
MiNTLib, GemLib, etc.

And finally, target executables (by opposition to target libraries) should 
not be installed on a host cross-environment, it is a nonsense since they 
can't be run on the host.
