Long before we get to libm issues, we have issues building on 4.10:

*** Error code 1
I don't know if the e_scalbf.c chanages cause problems down stream,
but this was built on:
FreeBSD harmony.village.org 4.10-PRERELEASE FreeBSD 4.10-PRERELEASE #18: Tue May 18 08:55:28 MDT 2004 imp@harmony.village.org:/home/imp/FreeBSD/4x/src/sys/compile/HARMONY i386
which is fairly close 4.10 release.
