+This patch fixes multiple definitions of 'extern inline' functions.
+
+c99 and gnu90 have slightly different semantics
+WRT symbol definition: http://www.greenend.org.uk/rjk/tech/inline.html
+
+gcc-4 defaults to gnu90 and works, gcc-6 defaults to gnu-99
+and fails to link aboot as:
+  alpha-unknown-linux-gnu-ld: Disabling relaxation: it will not work with multiple definitions
+  lib/libaboot.a(isolib.o): In function `prefetchw':
+  (.text+0x60): multiple definition of `prefetchw'
+  fs/ext2.o:(.text+0xe68): first defined here
+
+The change is to force gnu90 explicitly.
