tcmalloc: add config files for different platforms

The Linux config file was generated by autoconf and manually edited to
define PC_FROM_UCONTEXT for ARM, change size_t printf format specifiers to
zd instead of ld, and add a GCC compiler guard around the
HAVE_BUILTIN_EXPECT macro definition. The file is being committed into the
repository for the purpose of cross-platform compilation.

The Windows config file was copied from an older version of tcmalloc and
must be manually inspected before being used with the new tcmalloc version.

The Android and FreeBSD config files are just stubs and must be generated
by autoconf on those respective platforms before they can be used.

Added windows/mingw.h and windows/port.h to the list of allowed include
rules of the DEPS file in the top tcmalloc dir.
