Hi,

Many tests failed if gcc passes --no-add-needed to linker with
error messages like:

/usr/local/bin/ld:
/export/build/gnu/glibc/build-x86_64-linux/nptl/tst-_res1.o: undefined
reference to symbol '_res'
/usr/local/bin/ld: note: '_res' is defined in DSO
/export/build/gnu/glibc/build-x86_64-linux/nptl/tst-_res1mod1.so so
try adding it to the linker command line
/export/build/gnu/glibc/build-x86_64-linux/nptl/tst-_res1mod1.so:
