x86-64: Work around gold bug 13023
Gold has trouble assigning numbers to the location counter inside of
an output section description. The bug was triggered by
9fd67b4ed0714ab718f1f9bd14c344af336a6df7, which consolidated all of
the vsyscall sections into a single section. The workaround is IMO
still nicer than the old way of doing it.
This produces an apparently valid kernel image and passes my vdso
tests on both GNU ld version 2.21.51.0.6-2.fc15 20110118 and GNU
gold (version 2.21.51.0.6-2.fc15 20110118) 1.10 as distributed by
Fedora 15.
