Spike, the RISC-V ISA Simulator, implements a functional model of one
or more RISC-V harts.

The host package provides an alternative solution to qemu.

+Subject: [PATCH] riscv: disable precompiled headers
+
+While precompiling header, some toolchains fail with the message:
+
+    /path/to/toolchain/bin/ld: /path/to/sysroot/usr/lib/Scrt1.o: in function `_start':
+    (.text+0x54): undefined reference to `main'
+
+The patch totally disable precompiled headers.
