testsuite/ld-elf/textaddr8.d should be ld/testsuite/ld-elf/textaddr8.d.

I got this strange message with i386 ld:

cc -m32 -c -O2 -ffunction-sections -fPIC -o x.o x.S
./ld.32 -Ttext-segment 0xffffffff80000000 -m elf_i386 -o x x.o
./ld.32: warning: address of `text-segment' isn't multiple of maximum page size
./ld.32: Segment text-segment address ffffffff is bigger than maximum address
00000000
