 > Some of the powerpc CPUs supported by Buildroot are dual mode CPUs,
 > which means 32 Bit and 64 Bit mode is supported, and for any 64-bit
 > capable CPU, GCC defaults to using 64-bit, even if the toolchain tuple
 > starts with powerpc-* (and not powerpc64-*). This causes issues when
 > building toolchains with uClibc or musl.

 > In order to resolve this, we force GCC to understand we want to
 > generate 32-bit code, using the --with-cpu-32 option.

 > See here the gcc documentation for details about --with-cpu-32:
 > https://gcc.gnu.org/install/configure.html

 > See here for a discussion on the musl mailinglist about the error:
