I do not quite understand what you have done. Your first build was linux
headers then glibc? Without doing anything with gcc? If so, you cannot expect
gcc to know about the glibc you built. All those SEARCH_DIR lines come from gcc.
You can tweak the spec file of gcc. How to do that is described in the gcc
manual "gcc.info", section 3.15 "Specifying subprocesses and switches to pass
to them". It used to be described in LFS as "a bit of black magic"
basically, you run:
gcc -dumpspecs > spec-filename
then you edit spec-filename
then each time you use gcc, you have to type:
gcc -specs=spec-filename
