xtensa: make sure bFLT stack is 16 byte aligned ...
commit 0773495b1f5f1c5e23551843f87b5ff37e7af8f7 upstream.
Xtensa ABI requires stack alignment to be at least 16. In noMMU
configuration ARCH_SLAB_MINALIGN is used to align stack. Make it at
least 16.
This fixes the following runtime error in noMMU configuration, caused by
interaction between insufficiently aligned stack and alloca function,
that results in corruption of on-stack variable in the libc function
glob:
Caught unhandled exception in 'sh' (pid = 47, pc = 0x02d05d65)
- should not happen
EXCCAUSE is 15
