Joseph Myers Dec. 2, 2010, 4:35 p.m. UTC 
In <http://gcc.gnu.org/ml/gcc-patches/2010-10/msg02373.html> I noted:

    There are a lot of *broken* specs for different targets of the form
    "%{!dynamic-linker:-dynamic-linker /lib/ld.so}".  These treat
    -dynamic-linker as a no-argument option whose effect is to disable the
    passing of a -dynamic-linker option to the linker.  The intended
    effect is clearly to avoid passing such an option if the user
    specified a dynamic linker explicitly - but it doesn't have that
    effect as there are no specs to pass through an explicit
    -dynamic-linker option and its argument.  Thus, all these specs should
    be simplified in a subsequent cleanup to remove the
    "%{!dynamic-linker:}" parts.

This patch effects that cleanup for all the affected specs.  The way
to pass -dynamic-linker options to the linker, that actually works,
remains use of -Wl, just as before, and options passed that way will
reliably come after, and so overrive, the default -dynamic-linker
options from LINK_SPEC.
