I used the spawn line from gcc.log which includes a -B.
I've looked further and I'm flummoxed. I ran the testsuite with a
--tool_opts='-save-temps -v'. gprof-7.o is identical with the command
line version, as you'd expect. I took the collect2 line from the
verbose log and ran that manually[1] and still got a test that passes.
I ran strace to track what static libraries are being used and
everything is under the build tree, except /usr/lib/crt{1,n,i}.o and
libc_nonshared.a. I especially checked libgcc.a and libgcov.a and
both are being pulled from build/gcc.
