I'm trying to create a toolchain that is as independent of the operating
system as possible. That is binutils, gcc and eglibc with its own
sysroot. That does mean that everything that is installed using that
toolchain is dependent on having that toolchain installed, and I'm fine
with that. Both gcc and binutils itself will also be dependent on the
eglibc that I'm installing.
LFS is doing almost the same, but it depends that you have root on that
machine, my goal is that my project is not.
My process is:
1) Compile and install binutils and gcc using the already installed
toolchain.
1.5) Install kernel headers.
2) Using the newly build binutils and gcc to compile and install eglibc.
3) Compile and install binutils and gcc again agains the newly installed
eglibc.
This might not seem that that since both binutils and gcc supports
sysroot. The problem is that I do not want to use the toolchain in a
chroot. So I must tell both binutils and gcc to use only the headers and
libraries that I installed, and not the ones provided by the host.
I've gotten that to work as well, but telling binutils and gcc to prefix
the path I've installed the toolchain into RPATH is where I'm stranded
now. Adding LDFLAGS to binutils was fine, so the RPATH is working as I
want now. But GCC is giving me a hard time.
My ldflags is
"-Wl,-I,$HOME/obj/tools/lib/ld-linux-x86-64.so.2,-rpath,$HOME/obj/tools/lib"
- but during bootstrap they are lost. How can I ensure that the LDFLAGS
that I want is being used in every stage? I've also tried setting
BOOT_FLAGS=${LDFLAGS} as well, but still no go.

That's BOOT_LDFLAGS. See also the configure option --with-boot-ldflags.

That did the trick. Thanks :-)
