Description

Trying to compile master on Alpine Linux edge (uses musl libc), gcc 8.3.0 and I am getting these errors:

The first error seems to an issue because of the non-inclusion of <dlfcn.h>

Another error with a test:

Research direction

Reproduce the build on Alpine Linux edge, then inspect src/preload/syscallbuf.c, src/test/ptrace_remote_unmap.c, src/log.h, src/kernel_abi.h, and the generated syscall-enum files named in the errors. Check the reported header, enum, and feature-macro failures across the C and C++ build; done means the project compiles and the affected test target builds successfully.
