If you want to compile uClibc with pthread support, then answer Y.
This will increase the size of uClibc by adding a bunch of locking
to critical data structures, and adding extra code to ensure that
functions are properly reentrant.

There are two versions of linuxthreads. The older (stable) version
has been in uClibc for quite a long time but hasn't seen too many
updates other than bugfixes.

The new version has not been tested much, and lacks ports for arches
which glibc does not support (like bfin/frv/etc...), but is based on
the latest code from glibc, so it may be the only choice for the
newer ports (like alpha/amd64/64bit arches and hppa).
