boost1{69,70,72}: fix build w/glibc-2.34

To quote the release-notes[1]:

> When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
> PTHREAD_STACK_MIN is no longer constant and is redefined to
> sysconf(_SC_THREAD_STACK_MIN).  This supports dynamic sized register
> sets for modern architectural features like Arm SVE.

This basically means that if the above applies, `#if PTHREAD_STACK_MIN > 0`
won't compile anymore because `PTHREAD_STACK_MIN` isn't a hard-coded
number, but `__sysconf (__SC_THREAD_STACK_MIN_VALUE)`[2].

The issue (for 1.69, 1.70, 1.72 - the other versions seem OK) was
reported upstream, but only for Solaris[3], however the corresponding
patches[4] seem to work as well for us.
