Change BB_EXTRA_VERSION: now it needs to contain any spaces/parenthesis

2017-07-04T14:01:12+00:00

Before this change, BB_EXTRA_VERSION of "" resulted in:

	"BusyBox v1.28.0.git () multi-call binary"

message, after the fix it is:

	"BusyBox v1.28.0.git multi-call binary"

While at it, eliminate BB_BT and BANNER single-use macros.

build: add a sanitizer debug option

2016-02-13T03:12:47+00:00

Building & running with ASAN is super helpful, so add a dedicated config
knob for it.  This way people don't have to guess at the right compiler
settings in order to get a good build.  We can just tell people to enable
this one option.

Benefits are: drops reference to out-of-line putchar(), fixes a few cases
of failed string merge.

Makefile: add missing libraries to LDLIBS

2015-08-17T15:05:55+00:00

Static build with CONFIG_PAM fails on Debian Jessie due to undefined
references to libdl and libaudit.

Static build without pam, but with libcrypt required fails as well due
to undefined references to libpthread.

Fix these two cases by adding the missing libraries to LDLIBS when
appropriate.

build system: use pkg-config to look up selinux libs

2012-10-20T19:01:26+00:00

Newer versions of libselinux has started linking against more libs.
Rather than continuing hardcoding things, switch to using pkg-config
to query for its dependencies.
