            Bug ID: 151140

When building webkit (or simply javascriptcore) on my aarch64 linux setup (with Tools/Scripts/build-{webkit,jsc} --gtk), I get undefined reference errors:

[820/823] Linking CXX shared library lib/libjavascriptcoregtk-4.0.so.18.3.0

Environment.cpp:(.text+0xbc): undefined reference to `dlsym'
Environment.cpp:(.text+0xc8): undefined reference to `dlclose'
collect2: error: ld returned 1 exit status

It turns out that the symbols are referenced from the isASanEnabled() function and -ldl is indeed missing from the linker's command line.
