cmd/go links mingwex and mingw32 libraries to every package it builds. This breaks when 2 different packages call same gcc standard library function pow. gcc linker appends pow implementation to the compiled package, and names that function "pow". But when these 2 compiled packages are linked together into the final executable, linker complains, because it finds two "pow" functions with the same name. This CL stops linking of mingwex and mingw32 during package build - that leaves pow function reference unresolved. pow reference gets resolved as final executable is built, by having both internal and external linker use mingwex and mingw32 libraries.
