Fix BSD regressions

Browse source 
The recent change to crt.S that aggressively aligns the system-provided
stack has been rolled back on non-Linux until we can find a better way,
since it can cause a segfault early in execution on several platforms.

This change fixes a regression in tcgetattr() and tcsetattr() on OpenBSD
and NetBSD caused by 4778cd4d27.

This change has been tested across the runitd test fleet which is green.
