lld linker error on mips64[el] linux targets.

[Wyvern]

When cross-compiling to mips64[el] linux targets using -Zbuild-stdgot lld linking error:

linking with `mips64-linux-gnuabi64-gcc` failed: exit status: 1

It seems like the C cross-compilation toolchain you used isn't compiled with non-executable stack. According to the error message lld doesn't allow this unless you explicitly tell it that it is ok to make the stack executable using -z execstack.

[Wyvern]

make the stack executable using -z execstack.

I tried this option, it doesn't work. And as I recalled mips64[el] targets can be compiled successfully without -z execstack before; not sure which change/commit change that.

"it doesn't work" meaning?

I assume this uses gcc12.
