Don't build libquadmath, libatomic and libitm if they have been
disabled.  Also, disable libssp so that none of its artifacts are built
or installed.

-Based on Richi's patch:
-<https://gcc.gnu.org/pipermail/gcc-patches/2024-April/648725.html>
-~~
-The following avoids re-walking and re-combining the instructions
-between i2 and i3 when the pattern of i2 doesn't change.
-
-Bootstrap and regtest running ontop of a reversal of
-r14-9692-g839bc42772ba7a.
-
-It brings down memory use from 9GB to 400MB and compile-time from
-80s to 3.5s.  r14-9692-g839bc42772ba7a does better in both metrics
-but has shown code generation regressions across architectures.
-
-	PR rtl-optimization/101523
-	* combine.cc (try_combine): When the pattern of i2 doesn't
-	change do not re-start combining at i2 or an earlier insn which
-	had links or notes added.
-~~
-But, since the patch affects code generation (for instance,
-libstdc++-v3/src/c++17/floating_from_chars.o), we limit the bailing out
-only when I2 hasn't been changed 1000x.  I've measured how many times
-at most is I2 unchanged during a bootstrap + regtest.
-x86: 134
-aarch64: 736 (gimple-match-1.cc)
-s390x: 635 (gimple-match-*)
-ppc64le: 620 (gimple-match-*)
-while certain pathological testcases trigger it more than 10,000 times.
-With the limit in place this patch doesn't affect common code.
