sci-misc/boinc: Fix VSYSCALL check for boinc-7.4.42
Gentoo-Bug: 578750
The configuration options were misunderstood.
- CONFIG_X86_VSYSCALL_EMULATION only enables a dmesg message if any
legacy application tries to use any vsyscall. If disabled, these
applications simply segfault with no output in dmesg.
- To make the old calls available, either
CONFIG_LEGACY_VSYSCALL_NATIVE or CONFIG_LEGACY_VSYSCALL_EMULATE
must be used.
Therefore the ebuild was reverted to check against the
CONFIG_LEGACY_VSYSCALL_NONE option, and warns the user if this is
set.
