Use individual entries for '-Wl,-rpath-link'

When the '-Wl,-rpath-link' option refers to several folders, we can
either use one single entry, like this:

    -Wl,-rpath-link,/path/to/folder1:/path/to/folder2:/path/to/folder3

...or we can use multiple entries, like this:

    -Wl,-rpath-link,/path/to/folder1
    -Wl,-rpath-link,/path/to/folder2
    -Wl,-rpath-link,/path/to/folder3

Because the '-rpath-link' requires full folder paths, using the one
single entry option can result in a very long argument.

While this shouldn't be a problem, at least *one* toolchain (the latest
version of the Tensilica toolchain for Xtensa processors) segfaults when
using arguments that are too long.

Because other toolchains might be affected and because using multiple
entries instead of a very long one doesn't seem to have any drawback,
this patch changes the arguments building logic to use multiple
'-Wl,-rpath-link' entries.
