Subject: Use -ffunction-sections -fdata-sections --gc-sections if the compiler supports
X-Git-Tag: 1_2_0~157
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7900b7b9b9956661d536223226c462c7f48fa40a;p=oweals%2Fbusybox.git

Use -ffunction-sections -fdata-sections --gc-sections if the compiler supports
it.  If nothing else, this gives us better granularity in bloatcheck.
