Error build for aarch64

[Vascom]

I am try to build megasync for Fedora. It is excellent built for x86_64, i686 and armv7hl arches. But aarch64 failed.
First error:

BUILDSTDERR: google_breakpad/common/memory.h: In member function 'uint8_t* google_breakpad::PageAllocator::GetNPages(unsigned int)':
BUILDSTDERR: google_breakpad/common/memory.h:117:15: error: 'sys_mmap2' was not declared in this scope
BUILDSTDERR:   117 |     void *a = sys_mmap2(NULL, page_size_ * num_pages, PROT_READ | PROT_WRITE,
BUILDSTDERR:       |               ^~~~~~~~~
BUILDSTDERR: google_breakpad/common/memory.h: In member function 'void google_breakpad::PageAllocator::FreeAll()':
BUILDSTDERR: google_breakpad/common/memory.h:136:7: error: 'sys_munmap' was not declared in this scope; did you mean 'munmap'?
BUILDSTDERR:   136 |       sys_munmap(cur, cur->num_pages * page_size_);
BUILDSTDERR:       |       ^~~~~~~~~~

Please correct it so we can use megasync on ARM 64-bit arch.

@Vascom Does the same error message still exist?
