kbuild: scripts/basic/fixdep segfault on pathological string-o-death
build scripts: fixdep blows segfault on string CONFIG_MODULE seen
The string "CONFIG_MODULE" appearing anywhere in a source file causes
fixdep to segfault. This string appeared in the wild in the current
mISDN sources (I think they meant CONFIG_MODULES). But it shouldn't
segfault (esp as CONFIG_MODULE appeared in a quoted string).
