Yep, feel to do so.

able to run on the host system (at least not without putting some
libraries in a lib subdirectory for whatever I'm trying to run.) This
happens a lot with Haiku anyhow, when the kernel, libroot or libbe (or
other system libraries) change a lot. But if I change the compiler things
should build at least.
Well, normally the stuff built with the target compiler doesn't need to
run on the the host platform. If host and target compiler are the same,
they need to, though. So whichever way you look at it, when you built on
Haiku with the native compiler, it must work correctly.

often. But it should be possible to upgrade that from within an existing
Haiku, without needing another system or completely reinstalling Haiku.
That's why I filed #7824. It should at least possible to actually cross-
built a new Haiku. Whether it will be possible to use the result to update
the system in-place is different question.

management will help, I don't know.
PM will definitely support system upgrades, if that's what you're
referring to. We will also improve the whole binutils-gcc-libstdc++
situation, because eventually libstdc++ will be split off into a separate
package. It will be possible to update it without updating gcc and vice
versa.
