Subject: [PATCH] buildinfo: strip sysroot and debug-prefix-map from compiler
 info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The openssl build system generates buildinf.h containing the full
compiler command line used to compile objects. This breaks
reproducibility, as the compile command is baked into libcrypto, where
it is used when running `openssl version -f`.

Add stripped build variables for the compiler and cflags lines, and use
those when generating buildinfo.h.

This is based on a similar patch for older openssl versions:
