2016-02-18	fix regression in SH/FDPIC dynamic linker	Rich Felker	-0/+2
	the dynamic linker was found to hang when used as the PT_INTERP, but not when invoked as a command. the mechanism of this failure was not determined, but the cause is clear: commit 5552ce52000855906a5cb4f08f2e456573cca51f removed the SHARED macro, but arch/sh/crt_arch.h is still using it to choose the right form of the crt/ldso entry point code. moving the forced definition from rcrt1.c to dlstart.c restores the old behavior. eventually the logic should be changed to fully remove the SHARED macro or at least rename it to something more reasonable.
2016-01-25	move dynamic linker to its own top-level directory, ldso	Rich Felker	-0/+146
	this eliminates the last need for the SHARED macro to control how files in the src tree are compiled. the same code is used for both libc.a and libc.so, with additional code for the dynamic linker (from the new ldso tree) being added to libc.so but not libc.a. separate .o and .lo object files still exist for the src tree, but the only difference is that the .lo files are built as PIC. in the future, if/when we add dlopen support for static-linked programs, much of the code in dynlink.c may be moved back into the src tree, but properly factored into separate source files. in that case, the code in the ldso tree will be reduced to just the dynamic linker entry point, self-relocation, and loading of libraries needed by the main application.
