[PATCH] D70764: build: reduce CMake handling for zlib

[Khem Raj via Phabricator via cfe-commits]

raj.khem added a comment.

this is now in master, and I am seeing build failures in cross-building clang, e.g. when building clang for arm on a x86_64 host. its resorting to finding, libz from buildhost instead of target sysroot ( using --sysroot) and failing in link step. e.g.

FAILED: bin/llvm-config
...
.... -o bin/llvm-config  -Wl,-rpath,"\$ORIGIN/../lib"  lib/libLLVMSupport.a  /usr/lib/libz.so  -lrt  -ldl  -ltinfo  -lm  lib/libLLVMDemangle.a
...

aarch64-yoe-linux-musl/aarch64-yoe-linux-musl-ld: /usr/lib/libz.so: error adding symbols: file in wrong format
clang-10: error: linker command failed with exit code 1 (use -v to see invocation)

you can see that its adding /usr/lib/libz.so to linker cmdline while cross linking.
