[Minios-devel] [UNIKRAFT PATCH] build: Define preprocessing symbol for library name

[Costin Lupu <costin.lupu@xxxxxxxxx>]

We define preprocessing symbols for library name in order to be able to protect
code based on the library name using #ifdef preprocessing directives (e.g.
"#ifdef __liblwip__"). The current solution also replaces dashes with
underscores given that we might have library names containing dashes (e.g.
for "pthread-embedded" library).
