The static library can be compiled with less featureful tools, but lacks key
features such as NSS.

+For Linux or Hurd, you want binutils 2.13 or higher. These are the only
versions we've tested and found reliable. Other versions may work but we
don't recommend them, especially not when C++ is involved.
Check the FAQ for any special compiler issues on particular
platforms.

- You must use GNU `binutils' (as and ld) if you want to build a
- shared library. Even if you don't want to build a shared library,
- we recommend you use them anyway. No one has tested compilation
- with non-GNU `binutils' in a long time.
-
- The quality of `binutils' releases has varied a bit recently. The
- bugs are in obscure features, but glibc uses quite a few of those.
- 2.10.1 and later releases are known to work. Versions after
- 2.8.1.0.23 may or may not work. Older versions definitely don't.
-
- For PPC you might need some patches even on top of the last
- `binutils' version. See the FAQ.
