1266877 - Update tooltool rust to target arm android-9

Status: RESOLVED FIXED

(Firefox Build System :: General, defect, P3)

Description

[Ralph Giles (:rillian)]

The official rust-std library builds target android-18 which causes unresolved symbols when linking into gecko, which targets android-9 and does not provide these functions:

    librul.a(std-4fda350b.0.o):std.0.rs:function f32::f32::log2::h90aa6ba577989944Mxa: error: undefined reference to 'log2f'
    librul.a(std-4fda350b.0.o):std.0.rs:function f64::f64::log2::hcebdfa55e23ecd4d5Na: error: undefined reference to 'log2'
    librul.a(std-4fda350b.0.o):std.0.rs:function fs::File::set_len::hf94cb2c64bf7fbb5Qrf: error: undefined reference to 'ftruncate64'
    /android/ndk-arm-18/sysroot/usr/include/unistd.h:177: error: undefined reference to '__page_size'

This bug is about updating the rust-std we use on official and integration build of fennec to something compatible which lets us link rust code.
