Sounds good to me, I've compare the soft-float folder in gcc and
glibc, fortunately here is only 4 difference,
list of changes in glibc/soft-fp in following section, including its
corresponding git sha1, I don't list file changes
which only update copyright years.

I can testing following changes on riscv* and nds32 target, but I am
not sure should we also test other arch before send a patch?
