and it's an excess CRLF indeed, but that's not a special case but
rather the standard output of pkg-config that comes with msys (0.25).
so whoever wrote the windows port decided to add an extra CRLF...

here is my lazy solution with a .cmd wrapper and it only works for
single line output.

------------------------------
:: pkg-config.cmd
@echo off
:: store last line with output into a varible
for /f "tokens=*" %%a in ('_pkg-config %*') do (
set out=%%a
)
:: truncate extra CRLF from line
if "%out%" NEQ "" (
   echo %out% | tr '\r\n' ' '
)
set out=
------------------------------

following your comments, i don't think there is an easy way to solve
the "CONFIG += silent" / CreateProcess situation unless we disable it
when the current OS is win32.
so "V = 1" is required and that's fine for me for the moment...
qmake "PKGCONFIG += libmarble libiconv libusb-1.0" "V = 1"

on the topic of sh.exe availability in PATH, i think we can safely
assume that user will have msys(-git) packages installed and most
likely sh.exe.
this is a dependency because our script are made for bash/sh.
