dev-lang/scala: Bump to 2.12.10

Thanks to toralf for reporting bug #623824, fixed with EAPI=7.

Thanks to Till Schafer for reporting bug #662184, fixed with:
use doc && einstalldocs

Thanks to Gentookh for reporting, fixed by only calling
check-reqs functions if ! use binary

+# Note: to bump scala, some things to try are:
+# 1. remove the https://dev.gentoo.org/~gienah/snapshots/${P}-ivy2-deps.tar.gz
+# and https://dev.gentoo.org/~gienah/snapshots/${P}-sbt-deps.tar.gz from
+# SRC_URI
+# 2. try emerge scala, with network-sandbox disabled:
+# FEATURES="noclean -network-sandbox" emerge dev-lang/scala
+# Check if it downloads more stuff in src_compile to
+# ${WORKDIR}/.ivy2 or ${WORKDIR}/.sbt or /root/.ivy2 or /root/.sbt
+# 3. tar up all the .ivy2 and .sbt junk into ${P}-ivy2-deps.tar.xz and
+# ${P}-sbt-deps.tar.xz and add them to SRC_URI, in ${WORKDIR}:
+# XZ_OPT=-9 tar --owner=portage --group=portage \
+# -cJf /usr/portage/distfiles/${P}-ivy2-deps.tar.xz .ivy2/cache
+# XZ_OPT=-9 tar --owner=portage --group=portage \
+# -cJf /usr/portage/distfiles/${P}-sbt-deps.tar.xz .sbt
+# 4. Add these tar files to SRC_URI (undo step 1).
+# 5. Try emerging it again, with network-sandbox, and create the bianry
+# tar archive:
+# FEATURES="noclean network-sandbox -test" USE="doc source" emerge dev-lang/scala
+# cd $WORDKIR
