LLVM/LLD error: unknown argument '--default-symver'

[tpgxyz]

Looks like this commit (https://github.com/akheron/jansson/commit/ca80d5127e56dd2ee056fdf3f4204017b78b89e0) does not takes into account that defult LD may be set to LLVM/LLD, finally producing error during linking:

P.s. Looks like only ld.bfd does support this https://bugs.llvm.org/show_bug.cgi?id=43452

Facing this issue. Would be great if we can get this merged @akheron
