make: relax definition of comment line

According to POSIX:

   Blank lines, empty lines, and lines with <number-sign> ('#')
   as the first character on the line are also known as comment
   lines.

Most implementations also include lines where the first non-blank
character is '#'.  Allow this as an extension.

Adds 0-16 bytes.
