Reproduced again, building libsass.

The output without -mxgot:
https://bf.mengyan1223.wang/assets/gcc-97787/libsass_so_lto_output.tar.xz

The output with -mxgot:
https://bf.mengyan1223.wang/assets/gcc-97787/libsass_so_lto_output_mxgot.tar.xz

Full console output with --verbose is included in the tarballs, named
console.log.

Actually I don't think it's a xgot issue... With or without -mxgot I got
exactly same error message.
