Subject: [PATCH] Revert "gdbsupport: remove unnecessary `#ifndef
 IN_PROCESS_AGENT`"

This reverts commit fe72c32765e1190c8a17d309fc3a7e1882d6a430.

It turns out it was wrong, libinproctrace.so does build its own
gdbsupport/tdesc.cc.  This broke the build:

    make[1]: Entering directory '/home/simark/build/binutils-gdb-one-target/gdbserver'
      CXXLD  libinproctrace.so
    /usr/bin/ld: gdbsupport/tdesc-ipa.o: in function `print_xml_feature::visit_pre(target_desc const*)':
