linux-libc-headers: Fix build failure by using fixed temporary file instead of pipe
This is a workaround for the following possible build failure.
*** Compiler lacks asm-goto support.. Stop.
When building linux-libc-headers we need to use binutils on build machine.
binutils v2.31 introduces a bug that could cause scripts/gcc-goto.sh to fail
when running in an environment where /tmp is rarely used, e.g. in docker.
