Allow multi-word "install" command.
Autoconf can determine that the correct install command includes flags,
e.g., "/usr/bin/install -c". When using this as a command, we can't
enclose the value in double-quotes, as that makes some shells use the
whole expression as a filename:
# this is the value returned by autoconf and stored in CT_install
$ ins="/usr/bin/install -c"
# if we call it with quotes, the command is not found
$ "${ins}"
bash: /usr/bin/install -c: No such file or directory
# removing the quotes lets it work as expected
$ ${ins}
/usr/bin/install: missing file operand
Try `/usr/bin/install --help' for more information.

1 Fix memset on PowerPC 8xx, by Nye Liu:

5 I am working on a powerpc 860 toolchain, but I am having problems
6 convincing glibc to not emit code that uses the dcbz instruction (CPU15
7 dcbX bug). The source of the problem is sysdeps/powerpc/power3/memset.S
