> -u is a linker option used to pretend a symbol is undefined, this option are common used for force pull-in weak symbol.

for forcing archive member extraction.

weak symbols are somewhat orthogonal.



================
Comment at: clang/test/Driver/riscv-args.c:5
 // RUN: %clang -### -target riscv32 \
 // RUN:   --gcc-toolchain= -Xlinker --defsym=FOO=10 -T a.lds %s 2>&1 \
 // RUN:   | FileCheck -check-prefix=CHECK-LD %s
----------------
Just place all linker options on one run line.

It decreases the number of RUN lines and additionally checks the order (though usually unimportant).
