When ASan testing is enabled on SPARC as per PR #107405, the ``` AddressSanitizer-sparc-linux :: TestCases/Linux/odr_c_test.c ``` test `FAIL`s on Linux/sparc64: ``` + projects/compiler-rt/test/asan/SPARCLinuxConfig/TestCases/Linux/Output/odr_c_test.c.tmp + count 0 Expected 0 lines, got 13. AddressSanitizer:DEADLYSIGNAL ================================================================= ==4165420==ERROR: AddressSanitizer: BUS on unknown address (pc 0x7012d5b4 bp 0xffa3b938 sp 0xffa3b8d0 T0) ==4165420==The signal is caused by a READ memory access. ==4165420==Hint: this fault was caused by a dereference of a high value address (see register values below). Disassemble the provided pc to learn which register was used. ``` The test relies on an unaligned access, which cannot work on a strict-alignment target like SPARC. Thus this patch skips the test. Tested on `sparc64-unknown-linux-gnu`.
