Subject: [PATCH] Recognize arm-* target triplets.
Reported by Sylvain Beucler <beuc@beuc.net>.

Subject: [PATCH] Recognize more ARM targets.
Suggested by Dale P. Smith.
* module/system/base/target.scm (cpu-endianness): Add cases for
"arm.*eb", "^aarch64.*be", and "aarch64". Change "arm" case to
"arm.*".
(triplet-pointer-size): Allow underscore as in 'aarch64_be'.
* test-suite/tests/asm-to-bytecode.test ("cross-compilation")["armeb-unknown-linux-gnu",
"aarch64-linux-gnu", "aarch64_be-linux-gnu"]: New tests.

Subject: [PATCH] VM: Allow the C compiler to choose FP_REG on ARM.
Reported by Rob Browning <rlb@defaultvalue.org>.
* libguile/vm-engine.h (IP_REG)[__arm__]: Remove explicit register

failures on ARM.
