Fix cross-compilation problems when CFLAGS contain target-specific options

Use BUILD_CCFLAGS and BUILD_LDFLAGS instead of CCFLAGS and LDFLAGS in
the build system when building files in the util directory which are
needed during the build process.  This avoids potential problems when
cross-compiling some of the options are not recognized as valid by the
host compiler.  (Addresses Sourceforge Bug #1261547)
