cmd/ld: set ELF ABI version for ppc64x

On ppc64, there are three ELF ABI versions an ELF file can request.
Previously, we used 0, which means "unspecified".  On our test
machines, this meant to use the default (v1 for big endian and v2 for
little endian), but apparently some systems can pick the wrong ABI if
neither is requested.  Leaving this as 0 also confuses libbfd, which
confuses gdb, objdump, etc.

Fix these problems by specifying ABI v1 for big endian and v2 for
little endian.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
