    libm: Exclude -Woverflow from -Werror in s_csqrtl.c for gcc47/i386.
    The issue is that a long double in gcc47 on i386 doesn't seem to be
    able to hold LDBL_MAX. At least a warning is generated. Cause
    unknown, might be a bug in gcc (or our gcc's configuration).
    gcc47 on FreeBSD/i386 does not show this behavior (no warning
    generated at least).
    Until we have a better clue, don't turn this warning into an error,
    even if -Werror is specified, so that building can go on.
