[fpc-devel] patch for rtl/linux/aarch64/cprt0.as

[Edmund Grimley Evans]

Clearly I don't really know what I'm doing with these start-up
files... but I found I needed this patch to build the Debian package
on arm64, so it's probably something for the AArch64 fixes branch.

I tried running the test suite with and without this patch, and it
appeared that webtbs/tw28089 went into an infinite loop without the
patch and passed with it, but I've never seen that test fail before,
and I don't see any connection with the patch, so I suspect there was
some kind of random race and this patch does not really make any
difference for the test suite.

By the way, the failures on powerpc and ppc64 look rather as if they
might be start-up-file-related:
