Old description:
Bootstrap of all platforms is broken post-gcc8.
Investigation so far:
* cross-tools build successfully
sysroot=.../cross-tools-$(arch)/sysroot
* cross-tools **builds** gcc_bootstrap:
* --with-sysroot=/
* --with-build-
sysroot=/work/generated.x86_64/objects/haiku/x86_64/packaging/repositories
/HaikuPortsCross-build/sys-devel/gcc_bootstrap/work-7.3.0_2018_05_01/boot
/cross-sysroot/x86_64/
* (I was trying to build 7.3.0 here, but when using gcc 8.x the same
path is used except the version differs)
The issue is the gcc_bootstrap attempts to create a binary and fails due
to being unable to locate:

These do exist within the sysroot though:

In the past, we saw this on RISC-V due to this issue which resulted in
similar errors:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89955
However, the STARTFILE_PREFIX_SPEC doesn't seem to be at play here since
all architectures see the issue, and only riscv64 redefine it.
As noted above, tried building gcc_bootstrap 7 with the gcc 8 cross-
tools... and the same error occurred. This seems to indicate that there
is some change within the initial buildtools (gcc8) cross-tools-build
causing the issue.
