Fix a security problem with the use of `chmod +w'.
{scripts,runtime}/Mmake:
Use `chmod u+w' rather than `chmod +w' on the installed files,
since `chmod +w' has the wrong effect with some versions of chmod.
When configure creates automatically-generated files, we do a
`chmod -w' on them to make sure that you don't accidentally edit
the automatically-generated file rather than the source `.in' file.
However, if the installed copies are write-only, then it causes
problems when installing a new copy on top of an old one.
Hence we turn write permission back on again on the installed copies.
The `chmod +w' command has the right effect on Solaris, OSF/1, and
SunOS, where it takes into account the umask. However, on IRIX and
ULTRIX, `chmod +w' does not take the umask into account, and so
makes the files world-writable, which is a security problem.
Hence, we now use `chmod u+w' instead.
