У вас уже собралось несколько пакетов с включённой LTO,
так что не сомневайтесь.

Это один из нескольких случаев, которые, видимо, были исправлены в gcc11:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96939
Наверное, можно пока отключить LTO для armh и оставить в спек-файле
соответствующий комментарий, а после перехода на gcc11 включить обратно.
