Whitelist a log1p failure in newlib
This might be an actaul newlib bug: it's not providing a range error
when taking log1p of -1e80, but it appears that this triggered a glibc
bug from a while ago that may have not been fixed in newlib. I'm not
sure why the bug is just manifesting now (the newlib sources haven't
changed for a long time), but the glibc version has some macros that
force the evaluation of particular floating-point expressions (one of
which produces the range error) that don't exist in newlib.
I'm OK whitelisting the error for the next release, despite it
technically being a regression. log1p isn't a standard function, and I
doubt embedded users are going to notice. That said, we should still
fix it.
