I posit that a better solution would be to add a test that our assumptions hold
to configure and bail out early on in a weird environment that would do things
like putting a single quote into $lockdir. Maybe packages using automake should
refuse to build in directories with absolute full names containing quote marks?
Something like: (in the generated configure)
case `pwd` in
*[\'\"]*)
echo "ERROR: cannot build reliably in a location named with quote
marks"
exit 1

There are likely more characters that can create problems down the line,
e.g. everything that has a special meaning to make(1), like the
space character U+0020 and the backslash itself.
I believe that space can be handled with proper quoting, but you have a
good point about adding backslash to the list---many non-POSIX systems
use it as a directory separator.
