compilers: handle -Wno-attributes= for GCC
For other reasons, Meson transforms "-Wno-x" into "-Wx -Wno-x" for GCC,
but this breaks with "-Wno-attributes=x" with:
```
cc1plus: error: arguments ignored for '-Wattributes='; use '-Wno-attributes=' instead
```
Suppress that workaround for -Wno-attributes=.
Closes: https://github.com/mesonbuild/meson/issues/13022
