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 ldso/mips: workaround for missing TLS macros in elfinterpret.c
     2 
     3 These macros declarations are missing, so gcc believes the code is calling
     4 a function, so any later linking will fail.
     5 
     6 Work this around by copying the mcaros from:
     7    libpthread/nptl/sysdeps/mips/dl-tls.h
     8 
     9 We can't include the header because of incompatible symbol declarations,
    10 so we just copy the macros for now.
    11 
    12 ---->  THIS IS A DIRTY HACK!  <----
