The implicit -mlong-calls from our vxworks configurations makes the
tail-call instructions differ from those expected by the
no_unique_address tests in gcc.target/arm.
This patch adds -mno-long-calls to the compilation commands, so that
we generate the expected sequences.
Regstrapped on x86_64-linux-gnu, also tested on arm-vxworks7r2.
Ok to install?
for gcc/testsuite/ChangeLog
* gcc.target/arm/no_unique_address_1.C: Add -mno-long-calls.
* gcc.target/arm/no_unique_address_2.C: Likewise.
