[build] Work around binutils quirk on OpenBSD 5.7

The assembler on OpenBSD 5.7 seems not to correctly handle the combinations of .struct and .previous used in unlzma.S, and ends up complaining about an "attempt to allocate data in absolute section". Work around this problem by explicitly resetting the section after the data structure definitions.
