Hello,
According to a comment in configure/configure.ac:
# We want to ensure that TARGET libraries (which we know are built with
# gcc) are built with "-O2 -g", so include those options when setting
# CFLAGS_FOR_TARGET and CXXFLAGS_FOR_TARGET.
but the current code does not ensure this.
I propose the patch below to fix this.

* configure.ac (CFLAGS_FOR_TARGET, CXXFLAGS_FOR_TARGET): Make sure
they contain -O2.
* configure: Regenerate.
