sci-misc/boinc: Fix VSYSCALL check for boinc-7.6.31
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. Package-Manager: portage-2.2.28
