uClibc-ng is missing implementation of floorl() and nearbyintl() from the math
library.

Fixes:

Baruch, All,

On 2017-03-30 08:29 +0300, Baruch Siach spake thusly:
> uClibc-ng is missing implementation of floorl() and nearbyintl() from the math
> library.

As dicussed with Thomas on IRC: the commit log is wrong. uClibc has had
nearbyintl() and floorl() for quite a good time now. They are just not
available for all archs.

So, here's a proposal for a better commit log:

    lvm2 needs floorl() amnd nearbyintl(), which uClibc does not provide
    for all architectures.

    The simplest solution is to just disable lvm2 for uClibc.

With that fixed:

Yann E. MORIN.
