Nope, there isn't. 

All I can say, I for one don't see any reason for treating
cross-toolchain packages any different from any other packages.
Besides of them facing the bugs in rpm/redhat-rpm-config which happen to
render packaging cross-toolchains difficult, and GCC's installation
directory conventions which happen to clash with the FHS, they are
ordinary applications.

Well, I happen package cross toolchains for Fedora for quite some
time[1]. Hans's avr packages inherited some aspects from these during
their package review.
