I tried to build a multilib encoder for Win32 in MSYS2/MinGW32 with GCC
9.2.0. The librraries for 10 and 12 bit precision passed (without any
Assembler optimization). The linking for the 8 bit precision library failed:

Please note that it compiled despite some ccache warnings. I don't know
if ccache has any impact here. I read in the patch notes when
media-autobuild suite introduced experimental ccache support that it
"needs to run at least once to have any effect", but that may only be
related to speed-up effects in subsequent compilations?

Fun and success!
