v1 2025-09-24:
During Boost library testing on aarch64-w64-mingw32, it appeared that 2^16
sections are not enough. It can be handled by using the bigobj format to extend
the total amount of sections to 2^32. This patch adds bigobj support to
AArch64 COFF in a similar way to how it is done for x86_64.
