Heiko, All,

On 2020-09-07 22:24 +0200, Heiko Thiery spake thusly:
> On aarch64 With the config option "--enable-mpers=check" the configure.ac
> script searchs for a 32bit compiler. When a matching compiler is found
> in the PATH some compatiblity checks are done. This can fail when the
> available kernel headers on host and buildroot target does not match.
> 
> Since buildroot does not support 32bit binaries when building for 64bit
> architecture (no -m32 option) we can disable this option unconditionally.
> 
> When disabling unconditionally also the configuration for toolchain using
> MUSL can be removed.
