TODO list for the uClibc 1.0.0 release:

+ *) Documentation updates:
+ *) Write a uClibc HOWTO document
+ *) Update README document
+ *) Update INSTALL document
+ *) Update docs/Glibc_vs_uClibc_Differences.txt document

+ perhaps using an abi tag magically embedded into each object)
for flagging config options that break the ABI. Options
such as UCLIBC_HAS_SOFT_FLOAT, UCLIBC_HAS_THREADS, UCLIBC_HAS_LOCALE,
and perhaps others (finalize list) produce a lib with a differing
ABI. Make it so apps cannot use an ABI mis-matched uClibc.

*) Cleanup / rewrite sysconf.c. It should get some information
from ldso (such as HZ). Other stuff it currently just makes
up, which is obviously wrong. Also bits/uClibc_clk_tck.h
needs to be updated at the same time to get proper HZ values.
