similar to: [klibc:master] use "--just-symbols" for compatibility with LLD

LLD uses "-R" as an alias for "-rpath", while LD uses "-R" as an alias for "--just-symbols". Use "--just-symbols" so that it's correctly supported for both linkers.

Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Use "--print-file-name=include" and "--print-libgcc-file-name" when using clang. Use cc-option to enable compiler-specific flags. Mark "bcmp" as not a builtin to prevent clang from using it. Signed-off-by: Bill Wendling <morbo at google.com>

Following is a list of issues that I hope to be addressed soon so we are in even better shape for -mm inclusion. 1) rebuild initramfs when content changes. > It is a simple matter of copying in usr/Makefile from the latest > -linus kernel and replace the 10 first lines with the content from > klibc Kbuild file. 2) havesyscalls.h is not deleted after make

I think that debug info is slowing a self-hosting build down. This build has been going for ages now and shows no sign of quitting. To reproduce, build a Release+Asserts build of clang. Then use that to build a Debug+Asserts version. Include all of the bells and whistles, like the clang-extras and compiler-rt libraries. The reason I suspect debug info is because of this stack trace: [morbo:llvm]

Merge s390 and s390x into s390. Compiled and tested on s390/s390x and i386. Also cross compilation for s390/s390x tested. This patch shouldn't break the build of any architecture.

Hi Bill Is this a recent regression? I recently changed the debug info verifier to fix a bug.

Hi Bill, Thanks for the testing case. Most of the time is spent on debug info verifier. I fixed a bug in r194974, now it takes too long to run debug info verification. Debug info verifier is part of the verifier which is a Function Pass. Tot currently tries to pull all reachable debug info MDNodes in each function, which is too time-consuming. The correct fix seems to be separating debug info
