autogen-native: fix script error when processing libguile
do_configure for autogen-native would fail if build directory path
contains '-I' characters, which is caused by the unsuitable sed script
when processing libguile.
Error log:

checking for GUILE... yes
awk: fatal: cannot open file `/buildarea1/poky/build /libguile/version.h' for reading (No such file or directory)
