Software :: Glibc 2.9 - Make Check - Fails On Rt/tst-cputimer With Timer Sig -12 - Invoked To Soon

I wish to install a new libc.so and have compiled the latest glibc (2.9.90) with the latest gcc (4.3.3) and the latest binutils (2.19, compiled with gcc 4.3.3). Compilation succeeded without errors, although not before I did some non- obvious things (e.g., I had to put '-march=i686' into my CFLAGS to avoid getting undefined symbol errors from the linker). 'Make check' also produced errors, a number of which I averted by doing non-obvious things (e.g., I had to copy iconvdata/gconv-modules and libio/tst-*.input from the source
directory to the build directory, and I had to export into the environment TIMEOUTFACTOR=2; the glibc documentation gave me no clue that I had to do any of those things). Now I am running into an error with rt/tst-cputimer that I do not know how to avert. I have run 'make check' 3 times; here are the 3 results. From rt/tst-cputimer1.out:

And from rt/tst-cputimer2.out:

Before running the 3rd 'make check', I increased TIMEOUTFACTOR
(to 3). It made no difference. From rt/tst-cputimer3.out:

I don't want to install the new libc.so until I can get all the tests to succeed, or, failing that, until I understand the significance of the error, and can intelligently dismiss it.
