x86 removed -pipe in commit 437e88ab8f9e2 ("x86/build: Remove -pipe from
KBUILD_CFLAGS") and the newer arm64 and riscv seem to have never used it,
so that seems to be the way the world's going.
Compile performance building defconfig on a POWER10 PowerNV system
was in the noise after 10 builds each. No point in adding options unless
they help something, so remove it.

This applies after the boot flags series, but easy enough to rebase if
necessary.
Thanks,
Nick
