GNU install says:

  -m, --mode=MODE     set permission mode (as in chmod), instead of

I takes this to mean that the default mode is 755, so you must use '-m'
for non-executable files.  

SGI's /sbin/install is more explicit

  -m mode      Set the mode of created files to mode, interpreted as an
               octal number.  The default mode for regular files and
               directories is 755.  The default mode for devices and
               named pipes is 666.  This option is ignored if given with
               -ln or -lns.

Unless you are the only person whose install program preserves the mode of
the original file, then the makefiles should explicitly set the mode for
executable files as well as the others, or perhaps just supply a script
with the desired behaviour.
