[Buildroot] malloc/rpl_malloc

[Jason Valenzuela <jvalenzuela@dspfl.com>]

I'm trying to compile some packages of my own and am coming up with some 
problems at link time with the malloc function. According to the uclibc 
FAQ, MALLOC_GLIBC_COMPAT should be enabled in order for the configure 
script not to define malloc() to rpl_malloc(). I went to the 
toolchain_build_ARCH/uClibc-0.9.29 and did a 'make menuconfig'. This 
option under 'General Library Settings->Malloc returns live pointer for 
malloc(0)' was indeed enabled, causing me to believe that the uclibc in 
my buildroot toolchain is already correctly set.

Now going back to the build_ARCH/MY_PACKAGE directory and checking the 
config.h, HAVE_MALLOC has been defined as 0 and the results in 
config.log shows that the configure script didn't think malloc() was 
compatible with the GNU libc version.
