There is an error:

../libtool: eval: line 950: syntax error near unexpected token `|’



You can ignore the line number, it depends on which program you are compiling. After some debugging, I find out that it looks like this was being caused by NM not being defined. Appears that it was being concatenated with a number of other commands within Libtool. When NM evaluated to nothing, this resulted in the syntax error mentioned above.

Solution:

export NM=nm
