[MiNT] problem with includepath in mintlib

[Miro Kropacek <miro.kropacek@gmail.com>]

Hi,

I'm playing with mintlib cross compilation and I again noticed strange 
bug which appears at least to me since I tried to cross compile mintlib 
for the first time.

It's the line in checkrules and buildrules:

-I$(top_srcdir)/mintlib -I$(top_srcdir)/stdlib 
-I$$(<$(top_srcdir)/includepath)

when I use $(top_srcdir)/includepath with some paths, gcc will 
completely ignore it. After closer look I see it just uses '-I' (but 
this is only visible in debug output -- on the screen that command looks 
right!) instead if -I/and/whatever/was/int/that/file ... funny thing, 
when I copy&paste the broken compilation command, compilation succeeded.

I tried this:

-I$(top_srcdir)/mintlib -I$(top_srcdir)/stdlib -I`cat 
$(top_srcdir)/includepath`

i.e. I did the same, just used another syntax -- and it works. My 
question is -- what's wrong here? It seems like some macro-expansion 
problem but I wasn't able to catch it.
