[COMMITTED 116/146] gccrs: Fix scan-gimple testcases on LE platforms.

[arthur . cohen]

From: Arthur Cohen <arthur.co...@embecosm.com>

gcc/testsuite/ChangeLog:

        * rust/compile/macros/builtin/eager1.rs: Switch to scan-assembler 
directive as the
        GIMPLE dump does not contain strings on LE.
        * rust/compile/macros/builtin/recurse2.rs: Likewise.
