If sort_bss_symbols_by_size is true, a shared library is built twice. The first build generates an unsorted output file, which is used to generate the symbol ordering file. The output of the second build is a shared library with its bss symbols sorted by their size. With this, the only user of symbol_ordering_file, libc, is migrated to use the new property, so we remove symbol_ordering_file support as well. Bug: 135754984 Test: Build and check the resulting libc.so has its bss symbols sorted. Change-Id: I5c892b44d82eb99cbc070cfa2c680be3087f3364
