*	fix system breakage window during make install due to permissions	Rich Felker	2014-01-15	1	-2/+1
\| \| \| \| \| \| \| \| \| \| \|	install.sh was wrongly waiting until after atomically replacing the old file to set the correct permissions on the new file. in the case of the dynamic linker, this would cause a dynamic-linked chmod command not to run (due to missing executable permissions on the dynamic linker) and thus leave the system in an unusable state. even if chmod is static-linked, the old behavior had a race window where dynamic-linked programs could fail to run.
*	fix mv usage in install.sh to avoid bogus interactive prompting	Rich Felker	2013-12-03	1	-1/+1

*	replace system's install command with a shell script	Rich Felker	2013-08-17	1	-0/+65
	the historical (non-standardized) install command is really inappropriate for installing binaries/libraries on a system that utilizes memory-mapped executable files. rather than replacing an existing file atomically, it overwrites the existing file. this can cause running programs to see a partially-modified version of the file, resulting in unpredictable behavior, or SIGBUS. a MAP_COPY mode for mmap would get around this problem, but Linux lacks MAP_COPY. the shell script added with this commit works around the problem by writing temporary files and moving them into place. unlike the historical install utility, it also support a -l option for installing a symbolic link atomically, via the same method.
