[obvious patch] add missing chmod to when copying headers

[Chris Demetriou <cgd@google.com>]

[-- Attachment #1: Type: text/plain, Size: 672 bytes --]

odd corner case when making/installing: if sources were checked out
with umask that denies group or other read (e.g. 077 or 027), most of
the installed gcc includes would come out group/other-readable but a
few wouldn't.
problem: missing chmods after copying the headers, in stmp-int-headers.
Since all of the rest of the headers are chmodded after copy, the
solution is obvious.


bootstrapped, verified permissions manually, committed as obvious.
