[Make-wifi-fast] Forum for LEDE build env questions?

[Marty]

I'm snagging on the MUSL redefinition errors when building LEDE image
and build tools.
/home/marty/lede/staging_dir/toolchain-arm_cortex-a9+vfpv3_gcc-5.4.0_musl_eabi/include/linux/in6.h:32:8:
error: redefinition of 'struct in6_addr'
/home/marty/lede/staging_dir/toolchain-arm_cortex-a9+vfpv3_gcc-5.4.0_musl_eabi/include/linux/in6.h:49:8:
error: redefinition of 'struct sockaddr_in6'
/home/marty/lede/staging_dir/toolchain-arm_cortex-a9+vfpv3_gcc-5.4.0_musl_eabi/include/linux/in6.h:59:8:
error: redefinition of 'struct ipv6_mreq'

I want to ask if it is a simple .config issue via make menuconfig, an
include path issue during compile, a linux header issue, etc. But I want
to ask in the right place.

TIA,
Marty
