[PATCH v2] build: fix cross compilation to x86_64

[Thomas Monjalon]

07/10/2026 11:26, Adrian Schollmeyer:
> If x86_64 is specified as target CPU instruction set (e.g. when
> cross-compiling *to* x86_64), the cpu_instruction_set may be set to
> x86_64, e.g. if it is derived from a Meson crossfile. However, while
> Meson uses "x86_64" as name for the x86_64 architecture, compiler
> options accept only "x86-64".
> 
> Introduce a conditional for handling this special case by changing
> cpu_instruction_set to the march-compatible value.

>  * more explicit comment about GCC/Clang requiring x86-64
>  * switch to x86-64-v2 feature level

Can this change be in config/x86/meson.build ?
