You are making progress, although it doesn't sound as if you agree.
Before, we knew there was a problem in the gmp-mpc-mpfr area. Now
we know that mpc is the problem, specifically that configure cannot
find mpc.h.
In 6.19 you should have installed mpc-1.1.0. My own log from a
successful build shows that mpc installed /usr/include/mpc.h,
/usr/lib/libmpc.* plus docs and info.
Do you have /usr/include/mpc.h in chroot ?
If not, and if you still have your shell's history from that stage,
try cursoring up to see how you configured mpc, and whether you did
run make-install. If not, use 'find' from outside chroot to look
for those files on /mnt/lfs/ in case the prefix was wrong.
The point of LFS is to learn from our mistakes, but if you get
nowhere with working out what went wrong, try rerunning the 6.19
instructions for mpc and see if the header and library are now
installed.
Alternatively, if you do have /usr/include/mpc.h in chroot then for
the moment I'm at a loss as to why the system is not looking there,
because the SEARCH items in Adjusting the Toolchain (6.10) ought to
check that it is looking at /usr/lib.
