Subject: buildsys: prevent make from searching for .config

Fixes:
make distclean
mkdir /.config
make -C test/API clean
Reading makefile `../../.config' (search path) (don't care) (no ~ expansion)...
make: *** ../../.config: Is a directory.  Stop.

write(1, "Reading makefile `../../.config'"..., 80) = 80
open("../../.config", O_RDONLY)         = -1 ENOENT (No such file or directory)
open("/usr/include/../../.config", O_RDONLY) = 6
fstat(6, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
read(6, 0x7f2fe3bfc000, 4096)           = -1 EISDIR (Is a directory)
