mips: executable-stack-in-shared-library

[cc me please]

Dear mips porter,

Upstream of one of my package is trying to provide a fix for the
lintian report:executable-stack-in-shared-library (*)

Basically the patch is as follow (**):

[...]
if (HWY_ARCH MATCHES "mips")
  target_link_options(hwy PUBLIC "LINKER:-z,noexecstack")
endif (HWY_ARCH MATCHES "mips")
[...]

Could someone please confirm this is the "right" patch. I fail to
understand why each and every source package would need to change the
default LDFLAGS value...

Thanks for suggestion/help
