Ever since an old patch version, it has (for reasonable security reasons) not supported patched with ../ in the filename. Many of our patches have been relying on this behaviour being OK, because we start off with an ancient patch version that didn't perform such checks. As soon as we need this behaviour after we build a newer patch though, we will have problems. So, let's change the policy. Patches are relative to where tarballs are extracted, rather than the "working directory" - e.g. have patches for `coreutils-9.4/src/cp.c` instead of `src/cp.c`. Keeping this consistent has a few implications; - patches are applied from the build/ directory in bash era now, with `-p0` - when patches are manually applied in the bash era, use `-p` as required, usually `-p1` - in kaem era where patches are always manually applied, `-p1` is used

In our context, some construct has decided that we don't support
|
|
XF mode (which is not true for the architecture, in general, as
|
|
this patch supports, but is sufficient for our strange environment).

Backport of commit 43ccb7e445329dd9557b42e7289a87a8071ab0f7.

[PATCH] libgcc: Enable XF mode conversions to/from DFP modes only if
|
|
supported
|
|
|
|
Some targets do not support XF mode (eg AArch64), so don't build the
|
|
corresponding to/from DFP modes convertion routines if
|
|
__LIBGCC_HAS_XF_MODE__ is not defined.
