libc/uClibc: add uClibc 0.9.30.3

This version has been released a couple of month ago, but it never reached
crosstool-ng tree. This may be linked to the fact that the current 0.9.30.2,
once patched, has nothing much different from 0.9.30.3, released.

I'm not including any patch with this upgrade, on purpose.

<`Kumba> ths: given the SHN_UNDEF thing is a hack, what's the preferred solution?

<ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls".

<ths> `Kumba: I haven't found a better one yet.

<ths> Probably marker symbols around the stub section, and then exclude it from the link map.

     7
<ths> This needs a ld change.
