While the build succeeded with other shells, the new dependency
generation would fail with "/bin/sh: line 1: -2: substring expression < 0"
for /bin/sh that happened to be bash-3.x. Using that notation
(name=${man:4: -2}) would also fail with dash and ksh-based
shells. Here's a fix:

Subject: [PATCH] build: adjust new rule not to depend on bash-4.x
* man/local.mk (man/dynamic-deps.mk): Use the same code to
derive FOO from man/FOO.1 as in the .x.1 rule below.
Using the more concise "name=$${man:4: -2}" is not portable enough.
