linux: Make profil_counter a compat_symbol (BZ#17726)
As indicated by Joseph's comment on BZ#17726, this symbol is most likely a historical ABI accident. This patch make it on both arm and sparc ABIs a compat_symbol. Checked against a build arm-linux-gnueabihf, sparcv9-linux-gnu, adn sparc64-linux-gnu to see if the symbol is still present. * gmon/Versions (libc) [GLIBC_2.31]: New entry. * sysdeps/unix/sysv/linux/arm/profil-counter.h (profil_counter): Make a compat_symbol. * sysdeps/unix/sysv/linux/sparc/profil-counter.h (__profil_counter_global): Likewise.
