Subject: build: remove explicit linker call to libm on macOS
/usr/lib/libm.tbd is available via libSystem.*.dylib and
reexports sanitizer symbols. When building for asan
this becomes an issue as the linker will resolve the symbols
from the system library rather from libclang_rt.*
For V8 that rely on specific version of these symbols
that get bundled as part of clang, for ex:
https://source.chromium.org/chromium/chromium/src/+/main:v8/src/heap/cppgc/platform.cc;l=93-97
accepting nullptr for shadow_offset in `asan_get_shadow_mapping`,
linking to system version that doesn't support this will lead to
a crash.
Clang driver eventually links with `-lSystem`
https://github.com/llvm/llvm-project/blob/e82f93890daefeb38fe2a22ee3db87a89948ec57/clang/lib/Driver/ToolChains/Darwin.cpp#L1628-L1631,
this is done after linking the sanitizer libraries which
ensures right order of resolution for the symbols.
