This should make it easier to analyze which parts of the build
are slow. The new package is only available in snapshot builds,
we don't want to ship it in production.
This ports the change from https://src.fedoraproject.org/rpms/compiler-rt/pull-request/67
to big-merge, which is a bit more complicated here due to the
explicit file lists.
By default compiler_rt_triple is the same as llvm_triple. For x86
it is i386-redhat-linux-gnu instead, with a symlink to the
llvm_triple i686-redhat-linux-gnu.
And then the file list also needs to ship that symlink.
Fix these errors on s390x by excluding the files on that arch:
File not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.s390x/usr/lib/clang/19/lib/s390x-redhat-linux-gnu/clang_rt.crtbegin.o
File not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.s390x/usr/lib/clang/19/lib/s390x-redhat-linux-gnu/clang_rt.crtend.o
File not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.s390x/usr/lib/clang/19/lib/s390x-redhat-linux-gnu/liborc_rt.a
Fix this error on i686 by explicitly creating the directory.
This matches what the implementation did pre-big-merge. I think
we do want to keep this directory structure consistent across all
arches.
Directory not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.i386/usr/lib/clang/19/bin
The list of supported sanitizers differs per target, and depending
on that some of these files may or may not be present. Use a
wildcard rather than explicitly listing this out.
https://github.com/llvm/llvm-project/pull/92456 added a new
libclang_rt.ctx_profile.a library.
Given that these all have a fixed prefix, I think it's fine to
use a wildcard for them instead of explicitly listing them.
Before I've used `%ifnarch` in the `<FILE>` included with `%files -f <FILE>`.
This produced this error:
```
RPM build errors:
File must begin with "/": %ifnarch
File must begin with "/": i386
File must begin with "/": i486
File must begin with "/": i586

File must begin with "/": pentium4
File must begin with "/": athlon

File must begin with "/": %endif
```
We can optimize this at any point in time later.
We had too many `*.so` libraries added to the `clang-devel` package.
Before we've added these implicitly by accident:
```
/usr/lib64/libLLVM.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libLTO.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libRemarks.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libclang-cpp.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libclang.so.19.0.0pre20240509.g943617d12ccbd3
/usr/lib64/libclang.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldCOFF.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldCommon.so.19.0pre20240509.g943617d12ccbd3

/usr/lib64/liblldMinGW.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldWasm.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.rtl.amdgpu.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.rtl.cuda.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.rtl.host.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.so.19.0pre20240509.g943617d12ccbd3
```
And now we're adding just these because these are the ones that used to
exist within the clang-devel package when it was still being built in
standalone mode:
```
/usr/lib64/libclang-cpp.so
/usr/lib64/libclang.so
```
