[jdk17u-dev] RFR: 8293887: AArch64 build failure with GCC 12 due to maybe-uninitialized warning in libfdlibm k_rem_pio2.c

[Dan Lutker]

Trivial backport to support building GCC 12 on Aarch64. Backport was not clean because jdk17 does not have support to disable warnings at the per file level and must disable the warning for the module.

Successfully build on Linux x64 and aarc64 with gcc 12.2.0.
