SVN-JH-20080403 : 6.9. Glibc-2.7 problem

The problems happen at :

I have been slowly and carefully ( and in fits and starts ) working my way
through a LFS build on my itty bitty PowerPC unit here.

When I get to this stage the process seems to freeze up.

What I mean is that the configure and the make ran fine. They took about 12
hours or so to get done.

However, the "make -k check 2>&1 | tee glibc-check-log" process has been
running for about 30 hours and I see no progress. In fact, for the past ten
hours or so the line on my terminal has been :

gcc test-tgmath2.c -c -std=gnu99 -fgnu89-inline -O2 -Wall -Winline

/sources/build/glibc-build/math/test-tgmath2.o.dt -MT

I am able to hit enter and see a carraige return. I can not ssh into the
machine any longer but the serial console is working.

I then hiy CTRL-C and waited for a while. Eventually I got back my prompt.

So then ... should I simply run the "make -k check" again ? Or maybe delete
the entire "glibc-build" directory and start over while being a tad more
patient?  Are there some "wait-longer-before-test-bailout" switches I can
add here for this slow machine?

Yes I realize that an embedded PowerPC type unit with 128MB of RAM is
pushing the boundaries of reasonable but there is no reason why the LFS
process can not succeed.
