standalone.

build: do not use 'private' in build.mk

Commit a4b52857d38427c784adeee48a3a513f89fd3450 introduced 'private'
keyword to solve a dependencies issue caused by the inheritance of
target-specific variable. The keyword however is only available since
make 3.82.

This patch removes the '-lstatic-thread-variable' option. Since we've
already added the library as one of the target's prerequisites and
compiling the target with '$^', that option is not needed.

Fixes #405.

reboot() - remove redundant "extern C"

The "extern C" specifier for reboot() is unnecessary because this is
already done in <sys/reboot.h> (include/api/sys/reboot.h).

osv::reboot(): don't halt on failure

osv::reboot()'s documentation says that if it fails to reboot it may
return. So don't call halt(). This halt() was only added as a stub for ARM,
so leave it only for the ARM case (and add a "FIXME" comment, as this
should be replaced by a real reboot).
