[PATCH 1/2] BaseTools/tools_def GCC: ARM/AARCH64: replace -save-temps with -pipe

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

For historical reasons, GCC builds for ARM and AARCH64 pass the
-save-temps command line option to GCC, which instructs the compiler
to preserve intermediate files, i.e., preprocessor output and generated
assembler. Given that this clutters up the Build directory, and slows
down the build, let's replace it with -pipe, which explicitly tells the
compiler to keep all intermediate representations in memory only.
