Commit ff45000fcb56b5b0f1a14a865d3541746d838a0a upstream.
The boot wrapper performs its own relocations and does not require PT_INTERP segment. However currently we don't tell the linker that.
Prior to binutils 2.28 that works OK. But since binutils commit 1a9ccd70f9a7 ("Fix the linker so that it will not silently generate ELF binaries with invalid program headers. Fix readelf to report such invalid binaries.") binutils tries to create a program header segment due to PT_INTERP, and the link fails because there is no space for it:
ld: arch/powerpc/boot/zImage.pseries: Not enough room for program headers, try linking with -N ld: final link failed: Bad value
So tell the linker not to do that, by passing --no-dynamic-linker.
