Then add -I to ld. We had the similar problem with as when we moved
to ELF. This is in gcc 2.7.2.3:

#undef ASM_SPEC
#define ASM_SPEC \
  "%{V} %{v:%{!V:-V}} %{Qy:} %{!Qn:-Qy} %{n} %{T} %{Ym,*} %{Yd,*} %{Wa,*:%*}"

This is in gcc today:

#define ASM_SPEC \
  "%{v:-V} %{Qy:} %{!Qn:-Qy} %{n} %{T} %{Ym,*} %{Yd,*} %{Wa,*:%*}"

People who use my new Linux binutils and gcc 2.7.2.3 have to patch
the gcc source or the specs file. Otherwise, "gcc -V" won't work.
