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 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch
2 The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
3 you have to actually list out the multilibs you want or you will end up with
4 just one when using targets like 'sh4-linux-gnu'.
6 The resulting toolchain can't even build a kernel as the kernel needs to build
7 with the nofpu flag to be sure that no fpu ops are generated.
9 Here we restore the gcc-3.x behavior; the additional overhead of building all
10 of these multilibs by default is negligible.
