This is very similar to Debian's Multiarch[1], but they have
/usr/lib/<arch-tuple> (less pollution of top-level /usr)
Indeed, such organization is ideal for cross-platform development:
* Libraries are installed in the same path, both for native and for cross
compilation
* As a result, normal packages in the distribution already have the
libraries in the correct locations for both native/cross compilation
* The packaging system (APT) was adapted to allow co-installation of such
packages (since the files don't conflict)
* At a later stage, the distribution began shipping complete toolchains
for all supported architectures -- built from exactly the same source (same
gcc, same binutils, etc.)
* I.e: a developer that need cross-compilation, install the wanted
toolchain(s) and all library packages are immediately available from standard
repositories.
I guess Fedora people that work on ARM/ARM64/RISC-V would love such a support.
