Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction struct to pass conform tests, but it ended up also changing the ABI for 32 bit builds. For 64 bit builds, changing the long to two ints works, but for 32 bit builds, it inserts 4 extra bytes. This leads to many packages randomly failing like bash that spews things like: configure: line 471: wait_for: No record of process 0 Bracket the new member by a wordsize check to fix the ABI for 32bit.
