Fabrice Fontaine 375f5dd1bd package/syslinux: disable documentation
Disable documentation to avoid the following build failure if a non
working asciidoc or a2x is found on the system:

asciidoc -o html/syslinux.html /nvmedata/autobuild/instance-3/output-1/build/syslinux-6.03/txt/syslinux.txt
/nvmedata/autobuild/instance-3/output-1/per-package/syslinux/host/bin/python3: No module named asciidoc

Setting {ASCIIDOC,A2X_XML}_OK to a value different of 0 will disable
html, man, xhtml and text documentation

Fixes:
 - http://autobuild.buildroot.org/results/47f876ccb56831cc1bb9e6c2f7dbce423581a0dd
