similar to: [klibc:master] Use -Ttext-segment to link shared library on all arches

When using clang+llvm and lld, I get the following error: ld.lld: error: -Ttext-segment is not supported. Use --image-base if you intend to set the base address Let's test whether linker is lld and use --image-base instead of -Ttext-segment. See llvm's rationale for not supporting -Ttext-segment: https://github.com/llvm/llvm-project/commit/4dc2fb123dcfe9a97ad6f3a1135053b74efd0bc9 Note

In the v3.6 kernel, many of the headers were split out into a uapi variant. klibc should be using those variants to compile. There is also a generated subdir, to seperate out generated headers. The old kernel header location needs to be included as well, because linux/compiler.h is available only in the base include directory. Signed-off-by: Robin H. Johnson <robbat2 at gentoo.org> ---

- Renamed IMAGE_BASE to LD_IMAGE_BASE_OPT. - Moved "-fcommon" to KLIBCREQFLAGS in scripts/Kbuild.klibc. - Remove "dash" warning fixes which have been upstreamed. - Conditionalize the inclusion of compiler flags by using the proper compiler name or "cc-option". - Added "-Werror" to "cc-option" to catch flags that cause warnings. - Retain

Use $(LD_IMAGE_BASE_OPT) instead of hardcoding --Ttext-segment, which lld does not support. This allows either --Ttext-segment or -image-base to be emitted based on the linker.

This reverts commit 9d8d648e604026b32cad00a84ed6c29cbd157641, which broke signal handing on some architectures. On m68k and parisc, signal return depends on a trampoline that the kernel writes on the stack. On alpha, s390, and sparc (32-bit), we can avoid this by providing our own function as sa_restorer, but we currently don't. Signed-off-by: Ben Hutchings <ben at decadent.org.uk>
