Note: this happens when trying to build the userland, for example jam -q @minimum-raw. The kernel builds fine.

The compiler is apparently supposed to provide builtins for most of these: ​http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0491h/BABICCBA.html . Why are these not found?

[kallisti5]

Because all the calls I see aren't prefixed with builtin?

[pulkomandy]

gcc is able to automatically replace calls to the standard functions (log1p, etc) with the builtins. But the symbols here are prefixed with two underscores, probably preventing this. So yes, we need to manually alias the glibc names to the gcc builtins.

[kallisti5]

eh. for now i'm throwing in the generics on arm to fill these holes. I'm for the "using musl for gcc4 someday" camp... using generics will get arm linking for now with minimum changes.

[waddlesplash]

The switch to musl for math fixed whatever problems remained here.
