Disable sccache on PGO builds
No description provided.
Currently, sccache doesn't work at all with clang-cl (PGO or not, bug 1476604), and newer versions of sccache that do the right thing for PGO flags with clang have other problems (see bug 1484897). The benefit of sccache on PGO+LTO builds is however limited (the profile-use half of the build doesn't benefit at all, and since it does LTO as well, it's the most time-consuming part of the build), so in order not to further block switching Linux builds to clang, let's just disable sccache on PGO builds for now (the earlier we can switch to clang, the more time it leaves to catch any problem that causes).
