autoconf has a test for strtod(), which assumes non-working
when cross-compiling, but it does work in both musl and
recent glibc.
coreutils (gnulib) does some additional tests on top of that,
but assumes working glibc when >= 2.8 when cross compiling.
It doesn't know about musl where the additional tests also
work, though.
