Linux Hexagon port doesn't define a specific 'struct stat'
but uses the generic one (see Linux commit 6103ec56c65c [*]
"asm-generic: add generic ABI headers" which predates the
introduction of the Hexagon port).

Remove the target specific target_stat (which in fact is the
target_stat64 structure but uses incorrect target_long and
ABI unsafe long long types) and use the generic target_stat64
instead.

Hi Laurent,

What is your plan for this patch? Technically this is a bugfix.

I see the code was released for 6.0, so not a regression. Probably 7.0
material now.
