gprofng: remove old interface with libcpc
interface with libcpc was used on Solaris. gprofng doesn't support profiling on Solaris. I removed this old code and other unused macros and variables. gprofng/ChangeLog 2024-04-29 Vladimir Mezentsev <vladimir.mezentsev@oracle.com> PR gprofng/31123 * common/hwcdrv.c: remove old interface with libcpc. * common/hwcdrv.h: Likewise. * common/hwcentry.h: Likewise. * common/hwcfuncs.c: Likewise. * common/hwcfuncs.h: Likewise. * common/hwctable.c: Likewise. * src/Dbe.cc: Likewise. * src/collctrl.cc: Likewise.
