I tried to build fiasco on alpine linux. This will fail with the following line:

Just this file or more/all files?
Their gcc enables PIC per default for security reasons. Since fiasco seems to need PIC disabled I have to tell the build system either to add -fno-PIC explictly, or to -D__KERNEL__ in any way. (I already tried DEFINES += -D__KERNEL__ or CFLAGS := -fno-PIC in Makeconf without success.)
What is the correct way to add such an option to the fiasco build system? Would it hurt to add -D__KERNEL__ per default on future releases? (After all it *is* a kernel.)
I'd add this to src/Makeconf: SHARED_FLAGS += -fno-pic
Does this fix it?
BTW, the above file looks very much like a jdb file. Is it correct that this file is compiled even when I configured fiasco to not include jdb?
This is file defines an API between kernel and user, and does not contain code.
