Make the "all" Makefile target more robust
This is a minor improvement to the robustness of the command for"make all", in the face of plausible future target names.- Use [[:alpha:]] instead of [a-z] because, in POSIX BRE and ERE, whether [a-z] includes capital letters depends on the current collation order. (The goal here is greater consistency across systems, and for this it would also be okay to use [[:lower:]].)- Pass -x to the command that filters out the all target itself, so that the entire name must be "all", because a future target may contain the substring "all" as part of a larger word.
