[Buildroot] [git commit branch/2018.08.x] poco: disable fpenvironment for soft floating point configuration

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=d89859866f31ec7a3fa32237a2049c5a11ccff32
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.08.x

Many platforms don't provide all FPU features needed by Poco when
configured for soft floating point in their fenv.h header. So
disable fpenvironment for this configuration to avoid build breakage.
