> Just use -Wl,-dynamic-linker=/whatever/ld.so
-Wl,-dynamic-linker=/whatever/ld.so cannot be set permanently. It requires a
wrapper to inject such argument all the time, which is ugly.

Builtin specs of GCC is already very complicated (output from gcc-4.7.3
-dumpspecs on amd64):
...
*link:
%{!static:--eh-frame-hdr} %{m32|mx32:;:-m elf_x86_64}
%{m32:-m elf_i386} %{mx32:-m elf32_x86_64}
%{shared:-shared} %{!shared: %{!static: %{rdynamic:-export-dynamic}
%{m32:-dynamic-linker
%{muclibc:/lib/ld-uClibc.so.0;:%{mbionic:/system/bin/linker;:/lib/ld-linux.so.2}}}
%{m32|mx32:;:-dynamic-linker
%{muclibc:/lib/ld64-uClibc.so.0;:%{mbionic:/system/bin/linker64;:/lib64/ld-linux-x86-64.so.2}}}
%{mx32:-dynamic-linker
%{muclibc:/lib/ldx32-uClibc.so.0;:%{mbionic:/system/bin/linkerx32;:/libx32/ld-linux-x32.so.2}}}}
%{static:-static}}
...
writing an equivalent specs with prefixed dynamic linker is horrible.
Please consider sopport dynamic linker prefix by an extra configure option.
