GCC building: Still libquadmath-related failures on bare irons?

[Tobias Burnus]

Hello,

given that the has been quite some libquadmath-related configure work: 
Are there still build problems due to link tests if one cross-builds for 
bare-iron targets? Or not? (Cf. PR 46520)

If so, I would start to tackle them next.

(As work around, one can now use --disable-libquadmath; however, I still 
would prefer to fix it such that it works out of the box.)
