d1bcd2977c
The import target for kernel build now fails, due to setting libapps.a as the default value for the BIN variable. The fail happens when the ELFLD function passes the LDLIBS parameter (which contains BIN / libapps.a) for the linker. There is no rule to create libapps.a in the case of the kernel build, so the linker gives an error due to it being missing. This commit patches this behavior so that BIN is not appended to LDLIBS. Another option would be to implement a dummy rule to create libapps.a, but looking at the git history this is no longer wanted behavior, thus the error is patched like this.
