Bug#1110520: jpeg-xl: FTBFS on riscv64: undefined reference to `__cxa_call_terminate'

[Pranav P]

Hi,

This commit: 070b56b24b14ede21aaebd68b67c3a8670600d2f fixes those bugs.
How ever there is Splines test failing (not a test from the original list) in this commit which also gets fixed in some later commit.
The latest commit has all of the tests fixed.

Thanks,
Pranav
