Joseph, does this look right?
[BZ #17747]
The y0/y1/yn and j0/j1/jn functions provided a strong_alias
to the "l"-suffixed variants when no long double support was
being compiled. This breaks namespace conformance when the
basename versions conform but the l-suffixed ones don't.
Fixed by making them weak aliases instead.

[BZ #17747]
* math/w_j0.c [defined NO_LONG_DOUBLE] (j0, y0): Convert strong
alias to weak alias for j0l, y0l.
* math/w_j1.c [defined NO_LONG_DOUBLE] (j1, y1): Likewise.
* math/w_jn.c [defined NO_LONG_DOUBLE] (jn, yn): Likewise.
