[Buildroot] [PATCH 1/1] boost: fiber needs exception_ptr

[Fabrice Fontaine]

fiber needs exception_ptr because context is a transient dependency of fiber
that needs exception_ptr.
An other option would be to make boost fiber depends on boost context
(https://www.boost.org/doc/libs/1_67_0/libs/fiber/doc/html/fiber/overview.html)

Fixes:
