[PATCH v2] make: add INSTALL_STRIP variable

[PATCH v2] make: add INSTALL_STRIP variable

[Bagas Sanjaya]

In some environments (most notably embedded systems and small production
servers), it is often desirable to have stripped Git binaries due to
tight disk space constraint.

Until now stripped Git can be built wih `make strip install`. Add
INSTALL_STRIP make variable so that they can install stripped Git
binaries with `make INSTALL_STRIP=yes install`.

Also document stripping and using INSTALL_STRIP in INSTALL.

 Changes from v1 [1]:

   - install target depends on strip when INSTALL_STRIP is defined
     (sugested by Đoàn)

We may want to see this discussion[2] settled first, I think.
