Revert "packages: Update uClibc to 0.9.33.2"

This reverts commit dffb50340f4ed38531cc28a4373a879108e35f26.

The configs patch works for 0.9.31 but asks quite a lot of hard
questions for 0.9.33 and possibly unsets the choice of EABI for arm
after setting it with sed, which would be not-good.  For sanity just
keep uClibc at the older known working version.
