Perhaps the rest of my patch resolved those issues as I am unable to recreate
your issue when using my patch.  I just verified that I do NOT have BR2_USE_WCHAR
enabled (Toolchain Options ---> Enable WCHAR support   is NOT checked).  I could not
get libxml2 to compile at all without apply patches, but it didn't give any
issues related to wchar that I could see, it was because it was trying to build
stuff like the python module ...
