[Buildroot] [PATCH] package/collectd: Specify correct FP layout for PowerPC

[Andrey Smirnov]

PowerPC stores floating point as big endian, so, in order for
'network' plugin to work correctly (and potentially any user of
htond() in collectd's codebase), --with-fp-layout=endianflip as
opposed to --with-fp-layout=nothing needs to be specified during
configuration phase.
