Apparently the compiler sometimes bypasses the normal assembler, in
which case the asm label variant works. If the file contains any
inline asm, this bypassing is not done, and the assembler chokes on
invalid syntax. Inserting a dummy asm() statement in the test when
the compiler supports it makes sure no shortcuts are taken and the
test fails as it should.

This make NetBSD compile out of the box at the cost of a hack, but a

Currently the NetBSD FATE box adds -D_NETBSD_SOURCE to CPPFLAGS to work

headers, it is better to use a standard flag instead of a system-specific one.
As a sideeffect, this allows getting rid of a local _NETBSD_SOURCE definition.

The bug[1] is exposed when gcc decides to put some data in a common
section (i.e. data that will be used by more than one object). It will
suggest the data to be aligned, but binutils >= 2.19 will fail to
properly align it. Thus if the data requires any alignment greater
than 4, the application will crash.
The workaround prevents gcc from putting data in a common section,
instead putting it in a properly aligned section.
