All toolchain dependencies are circa the GCC 9.5.0 release:
GCC 9.5.0, binutils 2.38, gmp 6.2.1, mpfr 4.1.1, mpc 1.2.1, isl 0.18
Native:
* arm - mini2g, nano2g seems to work
- ipod6g boot hang on 9.5.0 (possibly leading to disk corruption)
* mips - xduoox3 seems stable so far
* m68k - binaries untested
Hosted:
* arm - binaries untested
* mips - erosq seems stable so far
* Android NDK - unchanged at GCC 4.9.4
