I do agree with this.

Back some time ago, it had been discussed that it was up to the user to
properly configure his/her compiler to the desired target system:

  Once upon a time (not so long ago...), there was the idea floating around [1]
  that uClibc should not care about the specifics of the target CPU, and should
  leave that to the compiler to decide. There even have been a mere attempt at
  doing so [2] [3], and even a consensus (at the time) [4] [5] but the code did
  not make it to the tree...

There was an updated tentative-patchset posted by me one year ago, but it
did not get applied (patches in the thread):
  http://lists.uclibc.org/pipermail/uclibc/2010-January/043535.html

I'm ready to rebase this patchset in the near future (say, ready before
FOSDEM) if that is still deemed a good way to go.

Yann E. MORIN.
