With my change, I got the following on ia64:

configure:8221: checking for ld that supports -Wl,--gc-sections
configure:8246: /export/build/gnu/gcc/build-ia64-linux/./gcc/xgcc
-B/export/build/gnu/gcc/build-ia64-linux/./gcc/
-B/usr/gcc-4.2/ia64-unknown-linux-gnu/bin/
-B/usr/gcc-4.2/ia64-unknown-linux-gnu/lib/ -isystem
/usr/gcc-4.2/ia64-unknown-linux-gnu/include -isystem
/usr/gcc-4.2/ia64-unknown-linux-gnu/sys-include -o conftest -x c++
-Werror -Wl,--gc-sections   conftest.c  >&5
/usr/local/bin/ld: Warning: gc-sections option ignored
configure:8252: $? = 0 configure:8256: test -z
                         || test ! -s conftest.err
configure:8259: $? = 0
configure:8262: test -s conftest
configure:8265: $? = 0
configure:8290: result: no

Without my change, it is similar. But the last one is

configure:8290: result: yes
