Comment (by kencu):

 It appears that Apple forgot to put "m4" in the CommandLineTools:

 {{{
 % ls /Library/Developer/CommandLineTools/usr/bin | grep m4
 gm4
 }}}

 but did put it in Xcode:
 {{{
 % ls
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
 | grep m4
 bm4
 gm4
 m4
 }}}

 so  when the DevloperDir is set to the CLTs, it triggers the installation
 prompt:
 {{{
  % DEVELOPER_DIR=/Library/Developer/CommandLineTools m4
 xcode-select: Failed to locate 'm4', requesting installation of command
 line developer tools.
 }}}
