coreboot-utils: fix build with llvm22
Pull in an upstream workaround for string truncation and fix an
uninitialized variable warning for a zero-length write.
This port could do with an update...
remove old x11 games that were already failing (xasteroids segfaulting
all over the place, at least on LP64; xpilot unable to connect to either
network or local server). ok tb
sdl2: fix build on i386 with LLVM 22 with
--disable-mmx --disable-sse --enable-sse2
various errors like this in MMX/SSE functions:
error: always_inline function '_mm_setzero_si64' requires target feature
'sse2', but would be inlined into function 'BlitRGBtoRGBPixelAlphaMMX'
that is compiled without support for 'sse2'
Update to a recent checkout to help build with llvm 22.
This is still not enough so temporarily use an axe until upstream fixes the remaining failures.
