Subject: build-sys: remove .la files after installation
X-Git-Tag: v197~12
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=ca25fde748dba7ee74e24dff2db6aff1d9faea00;p=elogind.git

build-sys: remove .la files after installation

Define KEEP_LA_FILES to keep them.

The hook is repeated because both install-exec-hook and
install-data-hook can install libraries and with parallel make
it's not possible to predict which one will run first.

tl;dr: Libtool .la files are not very useful for linking linux
libraries.
