[Buildroot] [Re: Valgrind compilation, with patch 3.5.0, need help]

[Damien Borie]

Ok I've applied successfully the patch 'bump to 3.5.0' and the large 
file patch. But I still have the same error
'checking for /proc/self/fd... configure: error: cannot check for file 
existence when cross compiling'
In 'configure' file, I can see that it result of a test of variable 
'cross-compiling'. If true, this error appears. I wonder if i can 
comment this and ignore this test...
