[bug#52186] [core-updates-frozen] Fix julia on i686-linux

[zimoun]

Hi,

This patch fixes all  broken Julia on i686 for core-updates-frozen.

Here, the patch could be conditionally applied depending on the
architecture.  It would avoid to rebuild all Julia packages for x86_64.
Although, they are not broke, I guess. ;-)

Let me know or please go ahead. :-)

[bug#52186] [core-updates-frozen PATCH v2 00/17] Fix Julia on i686-linux.

[zimoun]

Hi,

This series allow the julia package itself to build on i686-linux.  Then, it
fixes julia-* packages for i686-linux.  Note that julia and julia-* are
currently broken on master for i686-linux.

Both julia and julia-* are not impacted on x86_64 by  these changes.

These packages are still broken…

…but, IMHO, they can wait another round.  Only pycall (so pyplot) and gr are
failing on core-updates-frozen only.  The 2 other (sundials) are currently
broken on master.


Cheers,
simon

I made a couple of changes, mostly to use target-x86-32? and
target-64bit?. Patches pushed! Thanks.

I get 44 instances using ’string-prefix? “i686”’ vs 5 instance using
’target-x86-32’.  For my information, why is target-x86-32 preferred
here?

The string-prefix way is the current way on master to do it. On
core-updates we now have the different target macros to try to make all
the different times everything comes up have less chance of mistakes.

Thanks for explaining.  On a side note, these macros are not documented
in the manual, if I read correctly.
