Subject: ld: Build and install only unversioned libdep
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eba7b68cb023add7bdcbcc79ac6f3ce8e50952e1;p=binutils-gdb.git

ld: Build and install only unversioned libdep

Build only unversioned libdep and remove the installed libdep.la since
only a single libdep.so is needed.

	PR ld/27082
	* Makefile.am
	(libdep_la_LDFLAGS): Add -module -avoid-version.
	(libdep_la_LINK): New.
	(install-data-local): Depend on $(install-bfdpluginLTLIBRARIES)
	and remove libdep.la.
