[OE-core] ICU not working on powerpc (ppce500v2)

[Stefano Babic]

Hi,

I get an issue with icu (54.1, I am testing with Yocto-fido) on powepc
(I am testing with a p2020rdb from Freescale). Running icuinfo on target
I get:

ICU Initialization returned: U_INVALID_FORMAT_ERROR
Plugin file is: /usr/lib/icu/icuplugins54.txt

cldr.version and tz.version report errors and even simple tests do not
work. If I copy all .res files (icu54 directory) and then I set ICU_DATA
to that directory, it works - that means there should be an issue by
generating libicudata with PowerPc, or at least with e500v2.

I did exactly the same tests with an ARM platform (i.MX6), everything
works as expected. I suspect some issue due to endianess, but checking
the header in the libicudata it looks correct ( at least the first bytes).

I saw :

    icu: Disable the default LDFLAGSICUDT for target compile


and, as it looks like ARM related, I have already tried to revert it,
without any success. Does anyone have a hint ?

Best regards,
Stefano Babic
