Unable to build using mipsel-linux-gcc based on uclibc

[GoogleCodeExporter]

What steps will reproduce the problem?
1. ./configure --host=mipsel-linux
2. make
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.
How I understood the problem is in crosscompiler and different API for 
malloc_stats?

This looks to be a problem not in the cross-compiling, per se, but in the fact 
you're 
using uclibc.  It looks like uclibc has a different function signature for 
malloc_stats than glibc does.  I don't think malloc_stats is a standard posix 
function, so I guess this is reasonable, in a way.

I guess I can add a configure check that will handle this case.  It will be a 
little 
hard for me to test, unfortunately, since I don't have a uclibc system 
anywhere.  I'll 
try to make it available for the next release.

btw, as a temporary workaround for you personally, every place you see 
tc_malloc_stats(void) in tcmalloc.cc, just change it to tc_malloc_stats(FILE* 
fp).  
You may need to fix up a few call sites as well, but it should be pretty 
straightforward.

I already started changing tc_malloc_stats but I did not finished yet due some 
other 
obligations.  

I will try to help You as much as possible with testing when You prepare 
official patch 
...

I have an arm system where I am using ulibc also and am running into the same 
problem.   I attempted changing tc_malloc_stats(void) to tc_malloc_stats(FILE* 
fp), but it did not really help as there are other compile issues, and I am not 
sure if they are caused by my changes or more problems with ulibc.  Has anyone 
else gotten perftools to work with ulibc?

I've decided to close all the porting requests that don't have patches attached 
to them.  We're always happy to look at patches for new architectures, OSes, 
and compilers, but otherwise we are limited to the ones mentioned in the 
INSTALL file.  (Though, to be fair, I don't know how much we talk about 
compilers.)
