Subject: [PATCH] Add picolibc include directory to cc1plus spec
G++ doesn't use the cpp spec to add include directories, so we need to
add the picolibc include directory to the cc1plus spec element as well
as the cpp one. To make sure the libstdc++ headers can use
GCC-provided header directories, so use -idirafter instead of -isystem.
