[Thomas:
 - Don't create a new blockchain applications sub-menu for now, put
   this package in "Miscellaneous applications"
 - Do not select BR2_INSTALL_LIBSTDCPP, use depends on instead, and
   add the corresponding comment.
 - Do not select BR2_TOOLCHAIN_BUILDROOT_USE_SSP. Instead pass
   --disable-hardening, and let Buildroot pass the appropriate CFLAGS
   when hardening features are enabled system-wide.
 - Add missing BR2_TOOLCHAIN_HAS_ATOMIC dependency
 - Add quirky !(BR2_arm || BR2_armeb) || BR2_USE_MMU because the
   Cortex-M toolchains don't provide 8-byte __atomic intrinsics, but
   we don't have a good way to express that today
 - Add missing BR2_TOOLCHAIN_HAS_GCC_BUG_64735 due to the use of
   std::future
 - Use only one BITCOIN_CONF_OPTS assignment to pass all options]

+	  Bitcoin Core is an open source project which maintains and
+	  releases Bitcoin client software called “Bitcoin Core”.
+
+	  It is a direct descendant of the original Bitcoin software
+	  client released by Satoshi Nakamoto after he published the
+	  famous Bitcoin whitepaper.
+
+	  Bitcoin Core consists of both "full-node" software for fully
+	  validating the blockchain as well as a bitcoin wallet. The
+	  project also currently maintains related software such as
+	  the cryptography library libsecp256k1 and others located at
+	  GitHub.
