Ok for trunk, releases/gcc-16 and releases/gcc-15?
--
Add arm_v8_1m_mve_link to check that the options selected by
arm_v8_1m_mve_ok can link successfully.
Without a link test, the board specific ldflags might contain flags that
are incompatible with the linkage of the test case, for example the
built testglue.c from dejagnu is known to cause issues.
gcc/ChangeLog:
* doc/sourcebuild.texi (arm_v8_1m_mve_link): Document.
gcc/testsuite/ChangeLog:
* gcc.target/arm/pr110268-1.c: Use arm_v8_1m_mve_link.
* gcc.target/arm/pr110268-2.c: Likewise
* lib/target-supports.exp (arm_v8_1m_mve_link): New.
