basic_tools.m4 contains the line 'elif test "x$TAR_TYPE" = "aix";...' The comparison "x$TAR_TYPE" = "aix" can never be true. Adding an 'x' to both sides of the comparison prevents an erroneous match when the variable is the empty string.
Verified the test after successful build and reflecting changes 'elif test "x$TAR_TYPE" = "xaix";...' on generated-configure.sh file.
