Fast forward to upstream version containing a fix for a C++ incompatibility where isinf and isnan were incorrectly declared as C functions. This version also contains another useful change to disable the picolibc malloc implementation when built as a Zephyr module. This should improve error messages with Zephyr projects which use malloc but fail to define CONFIG_COMMON_LIBC_MALLOC. There are also minor cleanups in a few math functions in how FE_INEXACT exceptions are generated and AArch32 A-profile aeabi memcpy functions.
