include: Use printf(1) instead of shell loops for header symlinks
Using a shell for loop means we have to spawn a separate install(1) process for each header that is symlinked. This patch uses printf(1) to generate an argument list that has been prefixed with the correct number of ../ and then uses a single install(1) invocation. This reduces the number of execve() calls during make includes from 2442 (with D27622) to 1382. Running `make symlinks` in include/ now spawns 214 processes instead of 1276 without this patch.
